Allen-Bradley 1745-E103 SLC 500 Digital IO Module

The Allen-Bradley 1745-E103 SLC 100 Expansion I/O Module adds sixteen digital I/O points to an SLC 100 CPU in the SLC-500 family. It provides ten digital input terminals and six digital output terminals and is designed for 24V DC operation, enabling remote sensing and switching in compact automation cells. The expansion connects to the SLC 100 processor via a 1745-C2 ribbon cable, allowing straightforward, plug‑and‑play I/O augmentation without replacing the main controller. Typical applications include adding limit switches, sensors, and relay-controlled actuators for small manufacturing lines, machine-guarding circuits, and other discrete-control tasks where a compact expansion is required.
