Allen-Bradley | 1734-OB4 | POINT I/O

Product Description: Allen-Bradley 1734-OB4

The Allen-Bradley 1734-OB4 is a 4-channel digital output module in the POINT I/O system, designed to deliver 24V DC sourcing (PNP) output signals to field devices. It provides reliable control of external actuators such as solenoids, contactors, relays, and indicator lights, making it a space-efficient solution for discrete output applications in distributed automation systems.
