Allen-Bradley 1734-OB4 4-Channel DC Output Module

Allen-Bradley 1734-OB4 is a POINT I/O digital output module delivering four 24 V DC sourcing outputs for direct actuation of loads from a POINT I/O network. Each of the four channels provides a separate output that can energize 24 V DC devices such as solenoids, pilot lights, relays, buzzers, or other actuators, enabling compact control of machines and processes from a single, modular I/O module. The module mounts in a POINT I/O chassis and receives its power and synchronization from a common backplane via a compatible POINT I/O adapter; the common for the outputs can be daisychained from an 1734 adapter, a 1734-FPD power module, or a 1734-EP24DC supply. As part of the Allen-Bradley POINT I/O family, the 1734-OB4 shares the same 24 V DC logic level and backplane signaling as other Point I/O modules, offering straightforward wiring and scalable expansion for automation projects. The 1734-OB4 is a four-point DC output module designed for use with Allen-Bradley POINT I/O backplanes, providing a compact, modular solution for distributing control of 24 V DC actuators across industrial equipment.
