Allen-Bradley 1734-OB2 Point IO Digital Source Output Module

Allen‑Bradley 1734-OB2 POINT I/O Digital Source Output Module is a two‑channel, 24V DC digital output module that sources current to field devices from the POINT I/O bus. Each channel is controlled as a discrete output, with the module mapping to one byte of I/O data in the scanner’s data image so two loads can be driven per module. Designed for installation in a POINT I/O system, the 1734-OB2 integrates with compatible base hardware, such as a 1734‑TB or 1734‑TBS terminal base backed by the removable terminal block 1734‑RTB/RTBS and mounting base 1734‑MB. Typical applications include remote switching of 24V DC devices such as relays, contactors, signaling indicators, or other 24V actuators in distributed automation architectures, enabling I/O to be placed physically close to the loads. As part of the POINT I/O family, the 1734-OB2 offers modular scalability for expanding control of discrete loads across a plant floor while minimizing wiring and simplifying integration with Allen‑Bradley controllers and Studio 5000 configurations.
