Description

The Allen-Bradley 1745-E102 is a Basic I/O Expansion Unit designed for SLC 100 and SLC 150 programmable controller systems. It provides 16 I/O points, including 10 AC inputs and six hard-contact relay outputs, enabling existing control systems to expand their capacity for additional sensors, switches, relays, actuators, and other field devices. The unit supports both AC and DC loads through its relay outputs and provides high electrical isolation between field circuits and control logic. With flexible DIN-rail or screw mounting, status indicators, and straightforward ribbon-cable expansion, it is well suited for maintaining, expanding, and supporting legacy SLC automation systems.
