Allen-Bradley 1606-XLE240E 240W 24VDC 10A DIN rail power supply for Rockwell industrial control panels

Allen-Bradley 1606-XLE240E Essential Power Supply, 24-28V DC, 240 W, 120/240V AC Input Voltage — Specs, Review & Selection Guide

Controls engineers specifying a 24 VDC supply for a Rockwell-based panel consistently land on one question: does the 240 W rating of the Allen-Bradley 1606-XLE240E cover my PLC, I/O, and field device loads with enough margin, and is it the correct single-phase variant for my panel mains? This page answers both questions directly. The 1606-XLE240E is a switched-mode, DIN rail mounted power supply delivering 24–28 VDC adjustable output at up to 10 A and 240 W continuous, accepting single-phase 100–120 VAC or 200–240 VAC input — a rating that fits the majority of small to medium Allen-Bradley control panel builds.

Who Should Buy the 1606-XLE240E — and Who Shouldn't

This power supply is the right choice when all of the following are true for your project:

  • Your panel mains supply is single-phase 100–120 VAC or 200–240 VAC at 50 or 60 Hz — not three-phase.
  • Your combined continuous 24 VDC load current, including all PLCs, I/O cards, sensors, relays, and HMIs, sums to comfortably below 10 A after accounting for inrush peaks.
  • Your project is built on Allen-Bradley or Rockwell Automation hardware and single-vendor standardization is either specified or preferred.
  • DIN rail mounting in a suitably ventilated industrial enclosure is already part of your panel design.
  • An adjustable output range of 24–28 VDC is acceptable for all connected devices on the 24 V bus.

If your facility mains is three-phase, look at the 1606-XLE240E-3 instead. If your 24 VDC load exceeds 10 A, the higher-power 1606-XLE480E is the correct next step. If Rockwell ecosystem alignment is not a project requirement and lowest unit cost is the priority, third-party DIN rail alternatives are worth evaluating alongside this model.

What the 1606-XLE240E Does in a Real Control Panel

The Allen-Bradley 1606-XLE240E sits at the power conversion layer of a control cabinet. It takes single-phase plant mains — either a North American 120 VAC circuit or an international 240 VAC supply — and delivers a regulated, adjustable 24–28 VDC output at up to 10 A to every device on the 24 VDC bus. That bus typically includes a CompactLogix or ControlLogix I/O rack, distributed I/O modules, 24 VDC valve solenoids, discrete sensors, safety relays, and an HMI. The unit provides a front-panel DC OK green LED so operators and maintenance personnel can immediately confirm whether the 24 VDC supply is healthy without breaking out a meter.

Within the Allen-Bradley 1606 family, the 1606-XLE240E belongs to the Essential line — the cost-conscious tier positioned below the premium 1606-XLS series. The Essential designation means it delivers reliable industrial-grade performance suited to mainstream factory automation without the extended diagnostics and redundancy management features of the XLS line. For the majority of PLC and distributed I/O applications, the Essential tier is sufficient and delivers a lower per-unit cost than stepping up to XLS.

The output voltage is adjustable across the 24–28 VDC range, which is a meaningful detail when the panel supplies devices with different tolerance bands. Most 24 VDC industrial devices accept this range, but any strict 24 V-only loads should be verified before the setpoint is moved above 24 VDC. The unit requires convection cooling, which means adequate vertical clearance above and below the unit in the DIN rail layout is a hard installation requirement, not an optional best practice.

Typical System Architecture for a 1606-XLE240E Installation

The 1606-XLE240E occupies the AC-to-DC conversion node between plant mains distribution and the 24 VDC control bus. Here is how a typical deployment chain looks:

  • Plant single-phase mains (120 or 240 VAC) feeds the panel through a main disconnect and branch protection device (fuse or circuit breaker) that also protects the 1606-XLE240E AC input terminals.
  • The 1606-XLE240E converts the AC input to a regulated 24–28 VDC output, with the DC OK LED confirming healthy output status at the front face of the unit.
  • The 24 VDC output terminals connect to a Bulletin 1492 or similar DIN rail terminal block distribution row, which fans the 24 VDC bus out to individual branch circuits.
  • Branch circuits supply the CompactLogix or ControlLogix controller backplane power, distributed I/O modules, and field devices including sensors, relays, valve solenoids, and HMI panels.
  • Where load-sharing or redundancy is required, a second 1606-XLE240E can be deployed alongside the first with an appropriate OR-ing diode or redundancy module arrangement.

Where the 1606-XLE240E Gets Specified: Industries and Use Cases

Factory automation and discrete manufacturing represent the most common home for this power supply. Panel builders assembling Allen-Bradley-based machine control systems — conveyor lines, assembly cells, pick-and-place equipment — consistently specify the 1606-XLE240E as their 24 VDC backbone when the total I/O and sensor load lands in the 5–9 A range with comfortable margin below the 10 A rating.

Packaging and material handling OEMs building equipment destined for North American facilities standardize on this model because the single-phase 120/240 VAC input range covers both standard North American 120 VAC circuits and the 240 VAC single-phase circuits common in manufacturing environments. The 240 W rating covers a typical CompactLogix system with one or two I/O modules, a sensor network, and a valve manifold without approaching the thermal limit.

Maintenance and retrofit engineers replacing aging or obsolete 24 VDC supplies in existing Rockwell-equipped panels find the 1606-XLE240E a straightforward like-for-like replacement that preserves the single-vendor documentation and spare parts logic already in place at the plant.

Process skid builders and infrastructure controls teams using Allen-Bradley PLCs for building automation or utility monitoring also deploy this unit where the 24 VDC load is moderate and the control cabinet mains supply is single-phase.

Application Typical Deployment
Factory automation cell 24 VDC supply for CompactLogix rack, I/O modules, and proximity sensors
Packaging OEM machine Single-phase 120/240 VAC input, powering PLC, HMI, and valve manifold on one 24 V bus
Material handling conveyor 24 VDC rail for distributed I/O, safety relays, and photo-eye sensors

1606-XLE240E-3 240 W 10 A Three-phase AC Essential Same power rating but three-phase panel mains
1606-XLE480E Approx. 480 W Approx. 20 A Single-phase AC Essential Larger load banks exceeding 10 A at 24 VDC
1606-XLS240E 240 W 10 A Single-phase AC XLS Premium Harsher environments, advanced diagnostics, or premium feature requirements

If your load calculation approaches or exceeds 10 A, or if your panel mains is three-phase, the 1606-XLE240E-3 or 1606-XLE480E is the correct selection — check current availability and confirm your variant at LeadTime.ca.

Expert Verdict: Is the 1606-XLE240E the Right Call for Your Project?

The Allen-Bradley 1606-XLE240E earns its place on the BOM for controls engineers and OEM panel builders working within a Rockwell Automation ecosystem. The 240 W, 10 A output covers the practical load range of a CompactLogix or ControlLogix-based panel with a distributed I/O network, a sensor array, and valve solenoids — which is the majority of small-to-medium machine builds. The single-phase 100–240 VAC input range makes it compatible with both North American 120 VAC circuits and international 240 VAC single-phase supplies without modification. The front-panel DC OK LED and the adjustable 24–28 VDC output are features that matter during commissioning and maintenance, not just on paper. The Essential line positioning keeps the per-unit cost lower than the XLS series while retaining industrial-grade reliability for mainstream applications. For a plant already running Allen-Bradley PLCs and I/O, the documentation, spare parts logic, and vendor relationship are already in place — adding a 1606-XLE240E to the panel is a natural extension of that standard.

The honest limits of this model are equally important to state. If your facility mains is three-phase, this is the wrong part — you need the 1606-XLE240E-3, and connecting this single-phase unit incorrectly to a three-phase supply will be a commissioning problem. If your 24 VDC load exceeds 10 A continuous after a proper load calculation, the 1606-XLE480E is the right step up. If your application requires advanced PSU diagnostics, built-in redundancy management, or performance in extreme thermal or vibration environments, the 1606-XLS line is the appropriate upgrade path. And if Rockwell standardization is genuinely not a project requirement and cost is the primary driver, third-party 24 VDC DIN rail supplies at 10 A from established automation supply brands represent a legitimate alternative worth pricing.

From a procurement standpoint, the 1606-XLE240E is an active product with good distribution coverage across North America and international markets, which means availability risk is low for standard quantities. For larger project quantities or if lead time visibility matters before you lock in a commit date, working through a specialist automation distributor gives you real-time inventory confirmation, assistance validating the correct catalog suffix, and the ability to identify equivalent or substitute options if supply conditions change.

What Engineers Need to Know Before Ordering the 1606-XLE240E

Model-specific forum discussion on the Allen-Bradley 1606-XLE240E is sparse — searches across r/PLC, r/automation, PLCTalk, PLCS.net, MrPLC, and the Rockwell Automation support community returned no concentrated thread of model-specific feedback. What exists is broader 1606 family discussion, and the patterns in that discussion are instructive enough to be worth surfacing here.

The most consistently reported ordering mistake at the 1606 family level is the single-phase versus three-phase confusion. The catalog numbers 1606-XLE240E and 1606-XLE240E-3 are visually similar and deliver the same 240 W output, but they are electrically incompatible with each other's intended input source. Engineers who move fast on a BOM line item or copy a previous project's catalog number without checking the panel mains configuration are the ones who encounter this mistake. The second most common family-level error is selecting a power rating by habit rather than by load calculation — ordering a 240 W unit because it was used last time, without verifying that the new panel's 24 VDC load has grown and now warrants the 480 W model, or conversely paying for 240 W capacity when the application is a compact sensor panel that a 120 W unit would cover with margin.

The broader community perception of Allen-Bradley 1606 supplies is that they are reliable in service when correctly sized and installed, and priced at a premium relative to some third-party DIN rail alternatives. Thermal and ventilation issues — not product defects — account for the majority of field problems discussed. A 1606-XLE240E installed in a tightly packed, poorly ventilated enclosure running near its thermal limit is the scenario that produces nuisance shutdowns in the field. The convection cooling requirement is real; adequate clearance above and below the unit on the DIN rail is not a suggestion. When community members ask whether third-party 24 V 10 A supplies are acceptable substitutes, the consensus is that they can be in non-Rockwell-standardized environments, but in Rockwell-centric plants the single-vendor benefit — consistent documentation, spares coverage, and support alignment — is the practical reason to stay with the 1606 line. When model-specific guidance is limited and the selection decision matters, consulting a specialist distributor before ordering is the most reliable way to confirm you have the correct catalog number, the right power rating for your load, and an in-stock unit with a lead time that fits your project schedule.

Wiring and Installation Overview for the 1606-XLE240E

  • Mount the unit vertically on a standard DIN rail with adequate convection clearance above and below the housing — the unit relies entirely on natural airflow for cooling and derating applies if ventilation is restricted or ambient temperature is elevated.
  • Connect the AC input terminals (line, neutral, and protective earth ground) using appropriately sized conductors; an external fuse or circuit breaker on the AC input branch is required — the 1606-XLE240E does not contain an integrated input protective device.
  • Connect the 24 VDC positive and 0 V output terminals to your panel's 24 VDC distribution terminal block row, observing correct polarity; verify output voltage with a calibrated meter before connecting loads, and adjust the output setpoint within the 24–28 VDC range if required by your specific load devices.
  • Keep the unit physically separated from high-heat sources and high-frequency switching devices in the panel layout to avoid thermal accumulation and conducted noise on the DC output bus.
  • After initial energization with loads connected, confirm the DC OK green LED is illuminated and verify voltage at the farthest device on the 24 VDC bus under representative load conditions to validate cable sizing and terminal connections.

Full wiring diagrams, terminal torque specifications, and derating curves are available in the official Allen-Bradley 1606-XLE installation documentation. Always refer to current manufacturer documentation before wiring.

Wrong-Part Prevention Checklist Before You Order the 1606-XLE240E

Run through every item on this checklist before submitting a purchase order. Each point corresponds to a real ordering or installation mistake associated with the 1606-XLE family:

  1. Confirm input type: this is single-phase 120/240 VAC, not three-phase (do not confuse with 1606-XLE240E-3).
  2. Verify required 24 VDC load current (continuous and peak) does not exceed 10 A with adequate margin.
  3. Check cabinet mains voltage and frequency fall within the specified input range.
  4. Ensure DIN rail space and ventilation meet the unit's size and derating requirements.
  5. Confirm 24–28 VDC adjustable range is acceptable for all connected devices (some loads are strict 24 V).
  6. Verify environmental conditions (temperature range, enclosure, pollution degree) meet the unit's ratings.

If any of these checks raises a question before you order, contact the LeadTime.ca team — we can confirm the correct catalog number, check availability, and help identify the right variant for your specific panel configuration.

Frequently Asked Questions

Can I connect the 1606-XLE240E to a three-phase mains supply?

No. The 1606-XLE240E is rated for single-phase 100–120 VAC or 200–240 VAC input only. If your panel mains is three-phase, the correct model is the 1606-XLE240E-3, which delivers the same 240 W, 10 A output at 24–28 VDC from a three-phase AC input. Ordering the wrong input variant is the most commonly cited mistake for this product family — always confirm your panel mains configuration before ordering.

How much 24 VDC load can I actually put on a 1606-XLE240E before I risk overload trips?

The rated continuous output is 10 A at 24 VDC. In practice, a proper load calculation should sum the continuous current draw of every device on the 24 V bus, add an allowance for inrush or startup currents from devices like valve solenoids and contactors, and confirm the total stays comfortably below 10 A — a meaningful safety margin is standard practice. If your summed load approaches 10 A, the 1606-XLE480E at approximately 20 A is the appropriate step up rather than running the 240 W unit near its limit.

What is the practical difference between the 1606-XLE Essential line and the 1606-XLS line for everyday PLC panel use?

The Essential line, which includes the 1606-XLE240E, is positioned as the cost-effective industrial tier suited to mainstream factory automation where the primary requirements are reliable 24 VDC output and DIN rail convenience. The XLS line adds more advanced diagnostic and monitoring features, enhanced performance in harsher electrical and environmental conditions, and is typically specified when the application demands more than the Essential tier offers. For the majority of CompactLogix or ControlLogix-based machine panels, the Essential line is sufficient.

Does the 1606-XLE240E have built-in input circuit protection?

No. The 1606-XLE240E requires an external fuse or circuit breaker on the AC input branch. This is a standard requirement for switched-mode DIN rail power supplies of this type and must be accounted for in your panel design and protection coordination. Refer to the manufacturer's installation documentation for recommended external protection sizing.

Is the 1606-XLE240E a direct drop-in replacement for an older 24 VDC supply in an existing Rockwell panel?

In most cases yes, provided the existing installation uses single-phase AC mains input within the 100–240 VAC range and the 24 VDC load is within the 10 A rating of the 1606-XLE240E. Before replacing, verify the physical DIN rail footprint and terminal layout against the original unit, and confirm the output voltage setpoint is appropriate for all loads on the bus. Always check the current manufacturer documentation for any updated installation requirements.
