Short Description
Description:
The 1756-OB16IEF is a 16-point digital output module built for Rockwell Automation's ControlLogix® platform.
It generates high-speed, individually isolated DC outputs, making it perfect for demanding industrial automation applications.
Output: Sourcing (positive logic), 10-30VDC.
Isolation: Each output channel is electrically isolated to ensure maximum protection and signal integrity.
High-Speed Performance: With fast response times and support for Pulse Width Modulation (PWM), you can precisely control motors, valves, and other devices.
Diagnostics: Built-in fault detection and electronic fusing at each point help ensure safe and dependable operation.
CIP Sync Compatibility: Enables time-synchronized output updates for unified control across devices.
