Allen-Bradley 1746-OV32 SLC 500 Digital DC Output Module, 32 Points, 24V DC Sink
Allen-Bradley 1746-OV32 is a 32-point digital DC output module for the SLC 500 family, wired for current-sinking DC loads..
Overview
The module delivers 32 current-sinking transistor outputs from one SLC 500 slot, arranged as two groups of sixteen points per common. Outputs switch 5-50V DC loads at 0.5 A per point (30°C) and 8 A per module, the backplane draws 0.19 A at 5V DC, and signal delay is 0.1 ms on / 1.0 ms off. No electronic protection is provided, so external fusing is recommended. Wiring uses the supplied 40-pin connector (1746-N3) or the 1492 wiring system.
