Allen-Bradley 1492-AIFM4-3 4 Channel Feed-Through Analog Interface Module

The Allen-Bradley 1492-AIFM4-3 is a four-channel feed-through analog interface module designed for the Rockwell 1492 Wiring System, featuring three terminals per channel. Each channel can be configured as input, output, or as a 2-in/2-out combination, allowing flexible routing of analog signals between sensors, actuators, and the controller while staying within the 1492 family backplane. The module provides four independent analog channels in a compact feed-through form factor, enabling multi-channel signal interfacing in legacy automation environments. The 1492-AIFM4-3’s 3-terminal per channel arrangement supports the standard connection scheme used by 1492 analog interface modules, simplifying wiring and integration with compatible terminals and terminal blocks. As part of the 1492 Analog Interface Modules, it is intended for use in applications where discrete analog signals must be brought into or driven from a Rockwell Automation control system via the 1492 wiring ecosystem. For proper fit and operation, this variant should be cross-checked against the official 1492-AIFM4-3 datasheet and the specific rack/backplane configuration in your 1492 system.
