Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1756-OB16IEF is an Allen-Bradley ControlLogix digital output module providing 16 individually isolated DC outputs (10-30 V DC). It functions within peer-to-peer and CIP Sync architectures to deliver fast, PWM-capable switching and fault-mode control within ControlLogix systems. Typical applications include machine control, discrete device actuation, and timed output sequencing in industrial automation environments. Part number 1756-OB16IEF integrates isolated output channels with configurable fault behavior and precise output timing.
Best Suited For
- ControlLogix systems requiring digitally isolated fast PWM outputs
