Allen-Bradley 1756-OB16IEF | High-Speed 16-Channel DC Output Module with PWM & Peer-to-Peer (Isolated, 10–30V DC)

Overview

The Allen-Bradley 1756-OB16IEF is a high-speed digital DC output module for ControlLogix systems, designed with pulse width modulation (PWM) capability and peer-to-peer communication support. It provides 16 isolated 24V DC outputs within a 10–30V DC range, enabling precise control of high-speed devices such as valves, actuators, and servos in time-critical applications.

This module is ideal for real-time motion synchronization, position control, and other applications requiring deterministic high-speed signal output.
