Allen-Bradley 1746-IB32 SLC 500 Digital DC Input Module, 32 Points, 24V DC Sink
Allen-Bradley 1746-IB32 is a 32-point digital DC input module for the SLC 500 family, sized for 24V DC current-sinking sensors.
Overview
The module provides 32 sinking inputs at 24V DC nominal, operating from 15-30V DC at 50 degrees Celsius (15-26.4V DC at 60 degrees Celsius). The off-to-on signal delay is 3 ms and off-state current is 1 mA maximum. The backplane draws 103 mA at 5V DC with no 24V DC load; module power dissipation is 6.65 W (0.20 W per channel). General-purpose DC input applications connect through 1746-HT or 1746-HCA cables, and the module occupies a single 1746 chassis slot.
