Overview
The Allen-Bradley 1492-AIFM6S-3 is a feed-through isolated analog interface module designed for PLC and automation control systems. This 6-channel analog interface module provides isolated signal conditioning for analog inputs with 3-4 terminals per channel, making it a critical component for applications requiring galvanic isolation between input signal sources and control logic. The Series A design has been the industry standard for decades in industrial automation.
