Allen Bradley 1769-OB32 Product Overview
The Allen Bradley 1769-OB32 is a 32-point solid-state 24VDC source output module from the CompactLogix 1769-OB32 series, engineered for high-density digital control in CompactLogix and MicroLogix 1500 PLC systems. This module delivers fast, reliable transistor (PNP sourcing) outputs ideal for controlling solenoids, relays, indicator lights, motors, valves, and other DC loads in demanding industrial automation environments.
With 32 output channels segmented into 2 isolated groups of 16 points, the 1769-OB32 enables organized output management while conserving panel space. Its compact 1.5-slot form factor and flexible DIN rail or panel mounting options make it a versatile choice for control panel designs where space efficiency is critical.
Key Features
