Allen-Bradley 1746-ITV16 Digital Input Module

Allen‑Bradley 1746-ITV16 is a 16-channel digital DC input module for the SLC 500 system that provides fast‑response sourcing inputs from field devices wired to 24V DC. Designed to plug into a 1746 I/O backplane in a standard SLC 500 rack, it delivers discrete on/off signals to the PLC with rapid update times for time‑critical control tasks. The ITV16 operates over a 10–30V DC input range, making it compatible with common 24V DC sensors and switches, while each of its 16 inputs is monitored independently to support high‑density inputs in compact control cabinets. This module is typically used to read signals from pushbuttons, limit switches, proximity sensors, and other DC sensing devices, feeding the controller to execute fast logic decisions. When wiring, follow standard DC input practices and consider surge suppression across inductive loads to protect the module from transient voltages; overall, the 1746-ITV16 is a purpose‑built solution for integrating multiple DC sensing points into a 1746-based control scheme, enabling reliable, prompt state information for automation and machine control tasks.
