Allen-Bradley 1719-OB2 DC Output Module

Allen-Bradley 1719-OB2 is a two-point DC output module from Rockwell's 1719 Ex I/O family, providing two independent 23 V DC outputs for hazardous-location applications. This Ex I/O module is designed for Zone 2/Class I, Division 2 environments and mounts in a backplane powered by a dedicated 24 V DC supply (1719-PSDC). It ships with an 1719-TB8 eight-pole terminal base, enabling straightforward wiring of load circuits such as solenoids, relays, or other 23 V DC devices. The 1719-OB2 is intended to be used with Rockwell's Ex I/O system and supports the hazardous-location safety standard requirements for digital outputs, allowing controlled switching in environments where electrical isolation and intrinsic safety are essential. With two output channels, it serves compact control tasks where only a pair of loads need to be switched under control of a compatible controller. Ideal applications include hazardous-area control panels, safety interlocks, solenoid valves, or actuators in Zone 2/Class I, Division 2 installations, where a compact, intrinsically safe 23 V DC output solution is required. The module is designed for use with the 1719 backplane and DC power infrastructure, ensuring reliable operation within a Rockwell Automation Ex I/O network.
