Allen-Bradley 1746-IA8 SLC 500 Discrete Input Module

The Allen-Bradley 1746-IA8 is an 8-channel digital AC input module for the SLC 500 family that accepts 100–120 VAC field signals and presents them to the backplane as discrete inputs. It uses an open-style, removable terminal block for eight input points and includes per-channel LED indicators plus a module-status LED to confirm operation. Wiring supports Belden 8761 or equivalent cable and up to two 14 AWG conductors per terminal, making it a straightforward fit for SLC 500 racks handling 120 VAC field devices such as switches or relays. Designed to plug into a standard SLC 500 I/O chassis, the 1746-IA8 provides reliable eight-input capability for AC-based control circuits.
