Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1756-OB16E is an Allen-Bradley ControlLogix digitally fused DC output module providing 16 outputs (organized as two electronically fused groups of 8). It mounts in the ControlLogix chassis and supplies 10-31.2 V DC to field loads. It is typically used for driving DC loads such as solenoids, discrete indicators, or valves in industrial control systems within manufacturing, material handling, or packaging applications. The 1756-OB16E integrates into Logix-based automation platforms and supports standard output functionality with fault mode output behavior.
Best Suited For
- Discrete DC load switching in ControlLogix systems
- Integration with Logix-based control architectures
- Applications requiring per-group electronic output protection
- Field devices such as solenoids, lamps, or valves
