Product Description
The Allen-Bradley 1734-OB4 is a POINT I/O digital output module from Rockwell Automation’s Bulletin 1734 family. It provides four 24 V DC sourcing output channels for controlling field devices such as solenoids, relays, lamps, and other discrete actuators.
Designed for distributed I/O systems, the 1734-OB4 offers a compact footprint for installation close to field devices, reducing wiring complexity. When mounted on a DIN rail with POINT I/O terminal bases, it integrates seamlessly into ControlLogix® and CompactLogix® systems via EtherNet/IP adapters.
