Allen-Bradley 1769-OB32 32-Point 24VDC Source Output Module

Allen-Bradley 1769-OB32 CompactLogix 32-point 24VDC Source Output Module is a solid-state I/O module for CompactLogix controllers that provides 32 sourcing 24VDC outputs across two banks of 16 points each. It operates from a 20.4–26.4 VDC backplane supply and can source up to 0.5 A per point at 60 °C (1.0 A per point at 30 °C), with a module-wide maximum of 4.0 A at 60 °C (8.0 A at 30 °C). Off-state leakage is up to 1.0 mA at 26.4 V, and the on-state voltage drop maxes at 1.0 V when sourcing 1 A. Switching delays are about 0.1 ms on and 1.0 ms off, and it supports a surge of 2 A for 10 ms (repeatable every 2 seconds). Designed to drive 24VDC loads such as relays, coils, and other actuators, the OB32 provides high-density sourcing outputs within the CompactLogix I/O backplane, eliminating the need for separate power wiring for each channel while delivering reliable DC actuation across its 32 points.
