Allen-Bradley 1746-IV32 SLC 500 Digital DC Input Module, 32 Points, 24V DC Source
Allen-Bradley 1746-IV32 is a 32-point digital DC input module for the SLC 500 family, sized for 24V DC current-sourcing sensors..
Overview
The module packs 32 current-sourcing inputs into a single SLC 500 slot, arranged as four groups of eight points per common. Inputs operate from 15-30V DC at 50°C (15-26.4V DC at 60°C), the backplane draws only 0.05 A at 5V DC, and signal delay is 3 ms maximum in either direction. Total heat dissipation is 6.65 W (0.2 W per point), and Series A/B/C commons are internally fused at 2.5 A.
