Allen-Bradley 1734-OB4E 4-Point Digital Output Module

The Allen-Bradley 1734-OB4E POINT I/O 4-Point Digital Output Module provides electronically protected 24 VDC sourcing outputs for direct control of DC field devices such as relays, solenoids, indicators, and actuators in distributed industrial control systems. It delivers four DC sourcing outputs (1 A per channel; 3 A maximum module current) with transistor output technology, plus short-circuit protection and output diagnostics to help maintain system reliability. Part of the Bulletin 1734 POINT I/O family, this DIN-rail mounted module uses an open-style enclosure and supports installation in PLC-based automation, material handling, packaging lines, conveyors, and process control applications where modular distributed I/O is beneficial. Maintenance teams and system integrators rely on this module for repair, retrofit, expansion, or replacement in OEM equipment and other industrial automation networks, offering a compact solution for controlling DC-powered field devices and enabling simple integration with POINT I/O systems. The module draws 75 mA from the POINTBus at 5 VDC and provides 50 V continuous isolation, while operating from -20°C to +55°C.
