Allen-Bradley 1769-OB32 Source Output Module

Allen-Bradley 1769-OB32 is a CompactLogix 32-point solid-state 24V DC source output module for the 1769 Compact I/O bus, delivering two 16-point groups that source DC power to loads from the controller. It operates from a 24V DC supply with an operating range of 20.4 to 26.4V DC and offers fast switching with an on-delay of 0.1 ms and an off-delay of 1.0 ms, enabling reliable control of 24V devices. Each output point can source up to 0.5 A continuous (1.0 A at 30°C), with a per-module maximum of 4.0 A at 60°C (8.0 A at 30°C), plus a 2.0 A surge for 10 ms repeatable every 2 seconds; the on-state voltage drop is up to 1.0 V at 1 A, while the off-state leakage current can reach 1.0 mA at 26.4 V. The module provides isolation of 1200 V AC for 1 s or 1697 V DC for 1 s between each output point and the bus, and a working voltage of 75 V DC. Weighing approximately 450 g, the 1769-OB32 is designed for CompactLogix systems to provide reliable 24V DC source outputs for control of field devices, offering a compact, integrated solution for driving DC loads in industrial automation.
