Allen Bradley 1794-OB8 Flex I/O Digital DC Output Module

Product Introduction

The Allen-Bradley 1794-OB8 FLEX I/O Digital DC Output Module is a compact and reliable discrete output module designed for distributed control systems in industrial automation. As part of the FLEX I/O series from Rockwell Automation, it provides dependable 24V DC sourcing outputs for driving field devices such as relays, solenoids, and indicator lights.

With 8 output channels, the 1794-OB8 is well suited for applications that require moderate I/O density while maintaining flexibility in system design. Its modular architecture allows it to be installed close to field devices, reducing wiring complexity and improving system responsiveness.

The module is engineered for stable performance in industrial environments, offering consistent switching capability and compatibility with standard FLEX I/O terminal bases. Its DIN rail mounting and compact structure make it easy to integrate into control cabinets with limited space.
