Allen Bradley 1746-IB32 Digital Input Module

The Allen Bradley 1746-IB32 is a high-density digital input module designed for use with the SLC 500 series programmable logic controller (PLC) platform. With 32 sinking inputs operating at 24 VDC, this module allows for compact and cost-effective monitoring of multiple digital signals within industrial control systems.

Part of the trusted SLC 500 range, this Series D version features robust diagnostics and reliable performance in demanding applications. It is DIN rail or chassis-mounted via the standard SLC rack and integrates seamlessly into your control architecture.

Ideal for high I/O count installations such as packaging lines, material handling, and batch process systems where multiple on/off status signals are monitored.
