Allen-Bradley 1794-OB32P Flex IO Digital Output Module

The Allen-Bradley 1794-OB32P FLEX I/O module delivers 32 DC outputs for high-density remote control in distributed automation systems, enabling direct current-sourcing (PNP) control to field devices with a 24 V nominal supply. Each output can source up to 0.5 A, arranged in two groups of 16, with a maximum module current of 8 A; it operates within an output range of 10.2–31.2 VDC and an on-state drop up to 0.5 V, with off-state leakage up to 1 mA. Backplane current draw is 640 mA at 5 VDC, and isolation voltage is 850 VDC tested. Mounting is DIN Rail with FLEX I/O terminal bases, compatible with 1794-TB3, 1794-TB3S, and 1794-TBNF. The operating temperature range is 0°C to 55°C. Common applications include controlling solenoid valves, relays, motor starters, contactors, pilot lights, and alarms in packaging equipment, conveyors, assembly machinery, and other industrial automation environments where high-density digital output control is needed; maintenance teams and system integrators rely on it for expansion, replacement, retrofit projects, and modernization of distributed control systems.
