Allen-Bradley 1734-OB4E Discrete Output Module

The Allen-Bradley 1734-OB4E is a POINT I/O four-channel digital DC output module that provides four 24V DC sourcing outputs for controlling loads in distributed I/O networks. Each channel supports up to 3 A, and the module includes per-channel electronic short-circuit protection and channel-level fault diagnostics to help protect the I/O network and simplify troubleshooting. The module draws about 75 mA from the POINTBus and dissipates roughly 1.2 W, with a thermal rating around 4.1 BTU/hr, making it compact and energy-efficient for confined control panels. Typically used to drive discrete loads such as relays, solenoids, indicators, and other 24V DC devices, the 1734-OB4E is designed for integration into a Rockwell Automation POINT I/O system to provide scalable, modular output capability.
