Allen-Bradley 1734-OB8E 8-Point DC Output Module

The Allen-Bradley 1734-OB8E is a POINT I/O digital DC output module that provides eight 24V DC sourcing outputs for field devices within a POINT I/O network. It accepts a 24V DC supply in the 10–28.8V DC range and delivers a total of up to 3 A across all eight channels, with each output electronically protected to improve fault tolerance. The module interfaces with the POINTBus system, drawing up to 75 mA at 5V DC for its bus power, and dissipates up to about 2 W of heat; its compact footprint is roughly 2.21 in x 0.47 in x 2.97 in and it wires to a 1734-TB or 1734-TBS terminal base for field connections, making it suitable for distributed control architectures. Common applications include driving loads such as relays, solenoids, and indicators in industrial automation where eight discrete 24V outputs are required in a single device. The “E” designation denotes electronic protection for the outputs, providing safeguarded operation in fault-prone environments within Rockwell Automation’s POINT I/O ecosystem.
