Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1756-OX8I is an Allen-Bradley ControlLogix discrete relay output module featuring eight individually isolated relay outputs. It installs into a standard ControlLogix chassis to drive field devices such as contactors, indicator lamps, solenoids, and alarms. It supports both DC and AC output voltages and integrates with redundancy and timing functions in industrial automation systems. Part number 1756-OX8I provides relay-based switching within distributed or localized control architectures.
Best Suited For
- ControlLogix chassis in manufacturing and process control
- Driving contactors, pilot lamps, solenoids, and alarms
- Applications requiring both Normally Open and Normally Closed outputs
