Features:

  • Supports current (4‑20mA) and voltage signals for diverse sensor connectivity.
  • Enables quick module replacement without rewiring (1492‑RAIFM8‑3 variant).
  • Works with 1746, 1756, 1769, 1771, and 1794 I/O modules.
The 1492‑AIFM8‑3 is an 8‑channel analog interface module designed to connect analog field devices—such as temperature sensors, pressure transmitters, and flow meters—to PLC analog I/O modules. It supports both current (4‑20 mA) and voltage (0‑10 V) signal types, making it versatile for various industrial applications. The 1492‑AIFM8‑3 reduces wiring time and eliminates errors by providing a pre‑wired termination point between sensors and the control system, ensuring reliable signal transmission in manufacturing, process control, and automation environments.

The 1492‑AIFM8‑3 is available in a removable terminal block variant (1492‑RAIFM8‑3) that allows the entire wiring assembly to be disconnected from the module without removing individual wires. This feature significantly reduces downtime during module replacement or troubleshooting. The 1492‑AIFM8‑3 uses 1492‑RTB16N (screw style) or 1492‑RTB16P (push‑in style) terminal blocks, ordered separately. This design simplifies maintenance and minimizes wiring errors, making the 1492‑AIFM8‑3 ideal for applications requiring frequent module changes.

The 1492‑AIFM8‑3 is compatible with a wide range of Allen‑Bradley analog I/O modules, including 1746‑NI8, 1756‑IF16, 1756‑IF8, 1769‑IF8, 1771‑IL, and 1794‑IE8. It supports multiple cable types including 1492‑ACABLE C, H, F, E, TD, TC, UA, TB, TA, UD, WB, and R, with lengths of 0.5m, 1.0m, 2.5m, and 5.0m (custom lengths also available). The 1492‑AIFM8‑3 includes a 10‑32 x .312 thread roll type TT screw for shield grounding and is ITC (Instrumentation Tray Cable) rated for panel or conduit use.

The 1492-AIFM8-3 AB 8-Channel Analog Interface Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
