Allen-Bradley 1492-AIFM8S-3 is an eight-channel, feed-through isolated analog interface module (IFM) designed to bring analog signals into a control system. Each of the eight inputs uses three terminals and accepts 0–132 V AC/DC signals, enabling direct connection to sensors and transducers within the 1492 wiring system family. This fixed-terminal-block variant delivers galvanic isolation between field inputs and the backplane, and the module requires external loop power for its analog input circuitry.
