PRODUCT INFORMATION
Product Overview
Revision scope: These specifications describe 1746-IB32/C (Series C). Check the corresponding technical data before specifying another hardware series.
The Allen-Bradley 1746-IB32 is an SLC 500 current sinking DC input module. It provides 32 discrete digital input points. The unit operates with a nominal input voltage of 24 V DC. The module mounts directly into an SLC 500 chassis slot. Its sinking circuitry receives signals from current sourcing field devices. Backplane current consumption is 0.085 A at 5 V DC.
Each input channel includes signal delay filtering. The signal delay is 8 ms for ON transitions. The signal delay is 8 ms for OFF transitions. This filter response manages mechanical contact bounce from field switches. The 32-point density allows extensive digital input capacity in one rack location. Chassis-based mounting ensures integration with the SLC 500 backplane system.
