5094-IF8IH

Overview of Allen Bradley 5094-IF8IH

The Allen Bradley 5094-IF8IH is an advanced 8-channel, isolated analog input module designed for the FLEX 5000 I/O system. Built for demanding industrial environments, it integrates voltage, current, HART, RTD, and thermocouple signal measurement in a single compact module. The 5094-IF8IH supports direct connection to sensors and transmitters, offering precise analog data acquisition for process control, automation, and monitoring. With field-to-backplane isolation and between channels, it eliminates ground loops and ensures signal integrity in noisy installations. The module is rated for hazardous locations, features conformal coating options for harsh environments, and supports removal and insertion under power (RIUP), reducing downtime during maintenance. The flexible design and broad certification portfolio make it a reliable choice for critical automation applications.

Key Features of Allen Bradley 5094-IF8IH

• Eight isolated analog input channels—configure each for voltage, current, HART, RTD, or thermocouple signals.
• Supports wide input ranges: ±10 V, 0–10 V, 0–5 V; 0–20 mA, 4–20 mA.
• Compatible with J, K, T, B, E, N, R, S thermocouples and 2/3/4-wire RTDs for temperature measurement.
• High-resolution 24-bit multiplexed ADC for accurate signal acquisition.
• Field-to-backplane and channel-to-channel isolation (250 VAC) for clean signals and noise immunity.
• Certified for hazardous locations (ATEX, IECEx, UL) with an optional XT variant for extreme conditions.
• Supports hot-swap via terminal base with RIUP lever for reduced system downtime.
• Operates in wide temperature range: –40 to 70 °C (–40 to 158 °F).
• Robust field-side shield bar for improved electromagnetic compatibility.
• Easy integration with Allen Bradley Compact 5000 and FLEX 5000 control platforms.
