Allen-Bradley 1746-I08 Combination Input Module

Allen-Bradley 1746-IO8 Combination Input/Output Module provides eight discrete I/O points in a single SLC 500‑compatible module, combining four 120 VAC inputs with four relay outputs. It installs in any slot of a 1746 I/O chassis except slot 0 and communicates with the backplane to read input states and switch loads through its relay contacts. The AC inputs are designed for 120 VAC signals, while the four relay outputs are intended for switching loads in automation panels. This compact, plug‑in module enables monitoring of sensors and control of actuators from one device within the 1746 ecosystem, making it suitable for basic machine control, signaling, interlocks, and simple process‑control tasks.
