Allen-Bradley 1746-ITV16 16-Channel 24VDC Input Module

The Allen-Bradley 1746-ITV16 is a 16-channel fast‑response 24 VDC input module designed for the SLC 500 1746 I/O backplane, providing 16 discrete input points that source 24 VDC field signals from sensors and switches. As a Fast Response DC Input (Source) module, all inputs share a common 24 VDC supply and feed into the backplane to report their status to the controller, with a backplane current draw of 0.085 A. This module plugs into a standard 1746 I/O rack and enables rapid digital input detection, making it well suited for time‑critical applications that rely on quick sensing of devices such as limit switches, inductive or capacitive sensors, proximity switches, door interlocks, and other 24 VDC field devices in industrial automation. The ITV16’s sourcing (fast) configuration means the external field devices provide the positive 24 V to each input, simplifying wiring for common sensing topologies, while preserving a compact 16‑point footprint on the SLC 500 bus.
