Allen-Bradley 1746-IV32 Analog Input Module 32 Channel

The Allen-Bradley 1746-IV32 is a 32-channel digital input module for the SLC 500 PLC family, configured as a sourcing DC input block that reads 24 VDC signals from field devices. It groups inputs into four eight-channel sections, each with its own +24 V DC common, designed to mount in an SLC 500 I/O rack and connect to the controller via the standard 1746 backplane. The module operates on a 15 to 30 V DC input range at 50°C (15 to 26.4 V DC at 60°C) and provides 32 discrete input points for monitoring sensors, switches, and other 24 VDC logic signals, making it a scalable solution for industrial automation applications that rely on reliable sourcing inputs. intended for use in factory automation where 24 VDC sensing and straightforward wiring are priorities, the 1746-IV32 complements other 1746 I/O modules to support modular, expandable SLC 500 systems.
