Allen-Bradley 1715-OB8DE Digital Output Module

Allen-Bradley 1715-OB8DE is an eight-point digital output module designed for the 1715 Redundant I/O system. It provides eight DC outputs with a voltage range of 8 to 32 V DC, making it suitable for driving relays, solenoids, contactors, and other 24 V DC loads in industrial automation. As a Redundant I/O module, it is intended for high-availability installations and typically pairs with 1715 I/O bases such as the 1715-A3IO and termination assemblies to form a robust backplane connected to Rockwell Automation controllers via the 1715 I/O network. Each channel is independently switched under the programmable control of the PLC, enabling discrete load control while preserving system redundancy. With eight discrete outputs and compatibility with the 1715 family’s backplanes, the OB8DE integrates into existing 1715 networks to extend reliable remote I/O in applications like material handling, packaging, and automated machinery.
