Schneider RE22R2MYMR Modular Multifunction Timer Relay: Complete Specs, Pricing and Selection Guide

Controls engineers and panel builders searching for the Schneider RE22R2MYMR are typically staring at one of two situations: a failed timer in a running machine that cannot wait, or a new panel build where the timing logic needs to be right the first time without the overhead of a small PLC. The RE22R2MYMR is a DIN-rail mounted multifunction timer relay that accepts 24–240V AC/DC and delivers dual independent 8A switching outputs across a timing range of 0.05 seconds to 300 hours — four selectable modes, one compact 22.5mm footprint, no programming required.

If you have already confirmed this is the correct part for your circuit, check current pricing and availability for the RE22R2MYMR at LeadTime.ca — ships worldwide.

Who Should Buy the RE22R2MYMR — and Who Shouldn't

The RE22R2MYMR is the right choice when your control circuit needs flexible timing logic without a dedicated controller. Specify it when all of the following apply to your project:

  • Your timing requirement spans anywhere from 0.05 seconds to 300 hours and you want a single SKU to cover the full range
  • You need two independent 8A switching outputs to control two separate loads simultaneously or for contact redundancy
  • Your control power is anywhere between 24V and 240V AC or DC — the universal input eliminates the need for voltage-specific relay selection
  • The relay must mount on a standard 35mm top-hat DIN rail within a 22.5mm width allocation
  • Screw terminal connections are acceptable for your installation — M4 screw terminals, no plug-in connectors
  • On-delay, off-delay, pulse, or flash timing modes cover your application logic

If your load current exceeds 8A per output, or if you need more than two independently timed circuits, the RE22R2MYMR is not the correct part. The RE22R2MUM (16A single output) or a small PLC are the appropriate alternatives — both are covered in the variant comparison section below.

What the RE22R2MYMR Actually Does in a Control Circuit

The Schneider RE22R2MYMR is a modular multifunction timer relay from Schneider Electric's Zelio Time / Harmony Timer Relay family. Its core function is straightforward: it receives a trigger signal on its 24–240V AC/DC input, applies a user-defined timing delay or cycle, and then switches up to two independent 8A loads through its dual DPDT changeover contacts. The result is controlled ON/OFF switching with precision timing — without any PLC, ladder logic, or programming interface required.

Four timing modes are selectable from the front panel via a screwdriver-adjusted dial: on-delay (wait a defined period before turning output on), off-delay (turn on immediately, then wait before turning off), pulse (fixed on/off cycle), and flash (repeating blink pattern). This single device replaces what would otherwise require four separate fixed-delay relay models or a programmable controller for basic timing logic. The timing range of 0.05 seconds to 300 hours means the same unit handles a 50-millisecond solenoid pulse and a 12-hour overnight cycle without any model change. A dual LED indicator confirms power status and relay output state in real time, and a push-button diagnostic switch allows manual output activation during commissioning without waiting for the timing cycle to complete.

The contacts are rated at 250V AC with 8A maximum per output — appropriate for solenoid coils, motor starter coils, valve pilots, and indicator loads typical in industrial control panels. The CE, CSA, and UL approvals confirm compliance with both EU directives and North American safety standards, making this relay straightforward to specify for regulated installations on either side of the Atlantic.

Where the RE22R2MYMR Sits in a Typical System

The RE22R2MYMR occupies the timing logic layer of a control circuit — downstream of the control power supply and upstream of the final load devices. It does not replace a PLC; it handles the specific task of time-based switching so the PLC (if present) does not have to devote logic to simple delay functions.

  • Control power supply (24V DC, 120V AC, or 240V AC) feeds the relay input terminals directly
  • A trigger source — pushbutton, float switch, thermostat output, or PLC dry contact — applies the start signal to the relay input
  • The RE22R2MYMR applies the configured timing mode and delay, then closes or opens its two changeover contacts at the defined moment
  • Output A contact switches Load 1 (e.g., motor starter coil, solenoid valve, contactor coil) — up to 8A at 250V AC
  • Output B contact switches Load 2 independently (e.g., status indicator, second solenoid, fan relay) — also up to 8A at 250V AC

Industries and Applications Where This Relay Delivers

HVAC and building automation installers reach for the RE22R2MYMR when they need a fan to start on-delay after a compressor energizes, or when a pump requires a timed run/rest cycle in a cooling loop. The universal voltage input is particularly valuable in commercial building systems where 120V AC and 24V DC control circuits coexist in the same panel.

In manufacturing and machine automation, the relay is commonly used for motor start delays — ensuring adequate voltage stabilization before a fan or pump motor fully energizes — and for sequential load control where two devices (such as a heater and a fan) must energize in a defined time sequence using the dual outputs.

Water treatment and irrigation applications use the on-delay and off-delay combination to create pump run/rest cycles, protect float valves from rapid cycling, and time valve open/close sequences. The 300-hour maximum delay covers multi-day watering or treatment cycles in a single unit.

Food and beverage processing lines rely on the pulse and flash modes for ingredient mixer dwell times, filling and draining sequences, and pasteurization hold timers where a fixed on/off cycle must be repeated reliably without operator intervention.

Refrigeration systems use the flash mode for condenser fan pulse control and defrost cycle timing, while the off-delay mode enforces a compressor cooldown period before restart — a safety-critical function that a simple timer relay handles cleanly without a dedicated safety PLC.

Application Typical Deployment
HVAC fan sequencing On-delay starts supply fan 30 seconds after compressor energizes; single 120V AC control circuit
Pump run/rest cycling On-delay and off-delay combination creates timed irrigation or cooling pump cycles up to 300 hours
Motor soft-start delay On-delay holds motor contactor coil open for defined ramp-up period; relay output signals starter module
Sequential heater and fan control Output A energizes heater immediately; Output B brings fan on after defined delay — both from single relay
Defrost cycle control Flash mode creates repeating on/off pulse for refrigeration defrost heater cycling
Emergency stop cooldown dwell Off-delay holds equipment locked out for a defined cooldown period after E-stop before restart is permitted

Expert Verdict: Is the RE22R2MYMR the Right Timer Relay for Your Project?

The RE22R2MYMR earns its place as the default multifunction timer relay specification for a well-defined buyer profile: automation engineers and panel builders assembling control circuits for machines, HVAC systems, water treatment equipment, or food processing lines where the timing logic is straightforward and adding a PLC would be disproportionate in cost and complexity. The combination of a 0.05-second to 300-hour timing range in a single 22.5mm-wide unit, a universal 24–240V AC/DC input that eliminates voltage selection errors across mixed facilities, and two independent 8A changeover contacts that replace what would otherwise require two separate relay modules — these are genuine engineering advantages, not marketing copy. The dual LED indicators and push-button diagnostic switch are small features that save real time during commissioning and troubleshooting. The M4 screw terminals, while requiring a screwdriver, provide contact reliability in vibration-prone environments that push-clip connectors do not consistently match.

The RE22R2MYMR has real limits that are worth stating clearly. Both changeover outputs share one internal timing circuit — they activate and deactivate together. If your application requires two truly independent timing circuits with different delay values, you need two separate relay modules or a PLC, not this unit. If any connected load draws more than 8A (account for inrush current, not just steady-state), the contacts are at risk of welding or premature failure — in that case, the RE22R2MUM at 16A single output or an external contactor is the correct solution. Applications requiring precision timing tighter than the typical ±2–3% repeatability, remote monitoring, data logging, or integration with higher-level automation systems are outside the scope of this relay entirely — a small PLC such as those in the Siemens LOGO! or Rockwell CompactLogix families is the appropriate choice despite the higher cost.

From a procurement standpoint, the RE22R2MYMR is normally in stock at major authorized distributors with typical lead times of same-day to next-business-day for most locations worldwide. This matters significantly in emergency replacement scenarios where a failed timer has a machine down. Buying through a specialist industrial distributor rather than a generic online channel means access to technical documentation, wiring support, and stocked alternatives — including the RE22R2M and RE22R2MUM — if the initial specification requires adjustment during installation.

What Engineers Need to Know Before Ordering the RE22R2MYMR

Because community-specific discussion on the RE22R2MYMR model is sparse in public automation forums, the most valuable pre-order intelligence comes from documented field mistakes and the Wrong-Part Prevention Checklist that experienced engineers use when specifying this relay. The following points represent the categories of ordering and installation errors that repeatedly surface with multifunction timer relays in this class — and the RE22R2MYMR specifically, given its configurable modes and adjustable timing range.

The single most consequential specification error is underestimating load current. The 8A rating applies at 250V AC, and inrush current from solenoid coils and motor starter coils can significantly exceed steady-state draw. Engineers who specify this relay for a load that appears to be within rating based on nameplate running current, without accounting for inrush, will encounter contact welding or premature wear. The fix — using an external intermediate contactor rated for the higher inrush, switched by the relay's 8A contact — is straightforward but must be planned before installation, not discovered after a failed relay.

The second category of pre-order confusion centers on the dual output behavior. The RE22R2MYMR provides two DPDT changeover contacts that switch simultaneously — both respond to the same internal timing circuit. Engineers who need two outputs with different delay values from a single enclosure will be disappointed; that application requires two separate timer relay modules or a PLC with two independent timer rungs. If the application requires Output A to turn on at T=5 seconds and Output B to turn on at T=30 seconds, the RE22R2MYMR is not the correct device regardless of how attractive the compact footprint appears.

The timing scale misread is a well-documented commissioning mistake with adjustable timer relays. The screwdriver potentiometer on the RE22R2MYMR spans 0.05 seconds to 300 hours, and the scale units change across the dial range. Setting a 30-second on-delay while accidentally reading the scale in hours produces a 30-hour delay — the relay appears dead during testing, and the instinct is to replace a perfectly functional unit. Before commissioning, calculate the required timing value, identify which unit the dial scale reads at that position, and verify with the diagnostic push-button at a short test interval before setting the final value. This one step eliminates what is otherwise a confusing and avoidable troubleshooting session.

LeadTime.ca's team can assist with variant selection — including confirming whether your application calls for the RE22R2MYMR, the single-output RE22R2MUM, or the simpler fixed-delay RE22R2M — before the order is placed. When community data is limited and the stakes of a wrong-part order are a delayed machine or a failed inspection, specialist distributor consultation is the fastest path to a correct first order.

Wiring and Installation Overview

  • Verify control voltage at the panel power supply is within 24–240V AC/DC before connecting to relay input terminals — use a multimeter set to the correct AC or DC measurement mode
  • Mount on standard 35mm top-hat DIN rail; relay requires 22.5mm width with terminals facing forward for accessibility — confirm clearance before snapping into position
  • Connect trigger source (pushbutton, float switch, PLC dry contact) to input terminals; connect two load circuits to Output A and Output B DPDT contacts — verify NO or NC configuration before tightening
  • Tighten all M4 screw terminals hand-tight plus one-half additional turn; add cable strain relief or clips within 150mm of terminals to prevent vibration-induced loosening
  • After wiring, apply power and use the push-button diagnostic switch to manually activate outputs and confirm LED indicators and load response before relying on timing cycle — refer to the official Schneider Electric product manual for full commissioning procedures

Wrong-Part Prevention Checklist — Verify Before Ordering

Run through every item on this checklist before placing your order. One wrong answer means a different model is required.

  1. Do you need dual independent 8A outputs, or does a single 8A relay suffice? (Wrong: single-relay timer; Right: RE22R2MYMR dual output)
  2. Is your control voltage 24-240V AC/DC? (Wrong: 12V or 480V system; Right: RE22R2MYMR works 24-240V)
  3. Do you need timing from milliseconds to hours in one device? (Right: RE22R2MYMR range 0.05s-300h; Wrong: fixed-delay relay)
  4. Must the relay mount on DIN rail in a compact 22.5mm footprint? (Wrong: panel-mount or surface mount needed; Right: RE22R2MYMR DIN-rail)
  5. Are screw terminals acceptable, or do you need plug connectors? (Wrong: plug-in terminal required; Right: RE22R2MYMR screw connections)
  6. Do you need 8A per output, or is 5A or 16A required? (Wrong: 16A needed; Right: RE22R2MYMR at 8A)

If any item above sends you to a different model, contact LeadTime.ca with your application requirements and the team will confirm the correct RE22 variant or suggest an equivalent — including same-day stock check.

Frequently Asked Questions

Can the two outputs be set to different delay times — for example, Output A at 5 seconds and Output B at 30 seconds?

No. Both DPDT changeover contacts in the RE22R2MYMR share a single internal timing circuit and activate or deactivate together. If your application requires two independently timed circuits with different delay values, you need either two separate timer relay modules or a small PLC with two independent timer rungs. The dual outputs are best used for switching two loads that must energize and de-energize at exactly the same moment, or for contact redundancy on a single critical load.

My load is a motor starter coil rated 6A running but with 40A inrush — is the 8A output sufficient?

No. The 8A output rating of the RE22R2MYMR applies to the contact current, and motor coil inrush can far exceed nameplate running current. Attempting to switch a high-inrush load directly through the relay contacts risks contact welding and premature failure. The correct approach is to use the relay's 8A contact to energize an intermediate contactor or soft-start module rated for the actual inrush current. If a single 8A contact must handle the load directly, verify total inrush against the contact rating in the official datasheet before proceeding.

Will the RE22R2MYMR work on a standard 120V AC control circuit?

Yes. The 24–240V AC/DC universal input range includes 120V AC, which is within the rated band. Confirm your specific supply voltage is within range using a multimeter before applying power, as the relay's nameplate and datasheet are the authoritative references for the precise tolerance band around the rated input.

The relay appears to do nothing during testing — how do I tell if it is faulty or just set to a very long delay?

Before concluding the relay is faulty, rotate the timing adjustment dial to a short interval — such as a few seconds — and press the push-button diagnostic switch with input power applied. If the relay activates (audible click, LED state change, output switches), the relay is functional and the original setting was simply longer than expected, such as an accidental 300-hour setting instead of a 30-second setting. If the diagnostic switch produces no response, verify input voltage at the terminals with a multimeter and confirm the load wiring. Replace the relay only after eliminating power supply, wiring, and timing-scale errors as the cause.

Is the RE22R2MYMR a direct replacement for an existing RE22 module already mounted on the same DIN rail?

The RE22R2MYMR is part of the Schneider Electric Zelio Time / Harmony Timer Relay family and shares the 22.5mm DIN-rail footprint used across the RE22 product line. Physical compatibility within the RE22 family on the same DIN rail is a known characteristic of this product family. However, verify the specific terminal wiring, timing mode settings, and contact configuration of the unit being replaced against the RE22R2MYMR before treating it as a drop-in swap — differences in output configuration or mode availability between RE22 variants can affect circuit behavior after replacement.

What do the LED indicators show and how do I read a fault condition?

The RE22R2MYMR has two LED indicators: one confirms that power is present at the input terminals, and the second indicates the current state of the relay output contacts. If the power LED is off, input voltage is absent or below the operating threshold — check the upstream circuit breaker and control power supply. If the power LED is on but the output LED does not change state when the diagnostic switch is pressed, the relay contacts may be damaged or the internal timing circuit may have a fault. In that scenario, verify load wiring independently, then consider relay replacement.
