Allen-Bradley 1794-OB32P FLEX I/O 32-Point Protected 24V DC Digital Output Module
Allen-Bradley 1794-OB32P is a FLEX I/O protected digital output module with 32 sourcing 24 V DC transistor outputs, each protected against overcurrent and short-circuit faults.
Overview
The 1794-OB32P drives 32 sourcing loads from 10 to 31.2 V DC with electronic protection per channel — a tripped point is simply reset without replacing fuses. Groups are current-limited (6 A for channels 0…15, 8 A for channels 16…31, 14 A per module), and the module draws just 80 mA from the FlexBus. It seats on the 1794-TB32 or TB32S 32-point terminal base.
Key Features
- 32 protected sourcing transistor outputs (24 V DC nominal)
- 0.5 A per channel; group limits 6 A / 8 A; 14 A per module maximum
- On-state window 10…31.2 V DC; 0.5 V DC maximum voltage drop
- Off-state leakage only 0.5 mA maximum
- FlexBus draw 80 mA @ 5 V DC; 5.3 W maximum power dissipation
- Mounts on 1794-TB32 / 1794-TB32S terminal bases
- Open-style enclosure; DIN rail mount

Applications
The 1794-OB32P is used for high-density actuation of 24 V DC loads — solenoid valves, indicator stacks, relay coils and low-power actuators — where built-in short-circuit protection avoids fuse changes in packaging machines, assembly stations and distributed control panels.
