Allen-Bradley 1734-OV8E Digital Output Module

Allen-Bradley 1734-OV8E is an 8-channel 24V DC digital output module for the POINT I/O family. This sinking output module provides eight independent outputs that switch loads to ground, and it features electronic fuse-style protection for each channel. It is designed to mount in a 1734-TB or 1734-TBS Point I/O wiring base and communicates over the POINT I/O bus, making it suitable for distributed control architectures alongside other 1734 modules. Each channel is rated for 1 A nominal output current, with a module-level ceiling around 3 A total, and it operates from a 24V DC supply with a voltage range from 10 to 28.8V DC. The unit exposes 24V DC loads to a common return and offers 50V isolation, enabling safe integration with other logic and power circuits in industrial environments. Firmware revision 3.022 is associated with this model, and the module’s compact footprint matches the standard POINT I/O eight-channel format, delivering straightforward expansion for signaling, coil control, and other DC load applications. Typical uses include energizing relays, solenoids, and indicator lamps in automation cabinets or distributed I/O layouts where robust protection and quick response are required.
