Description
Product Description
The 1756-OF4 analog output module from Allen-Bradley is a high-performance ControlLogix I/O module engineered for precision analog signal control in industrial automation systems. Developed by Rockwell Automation, this module delivers four independently configurable analog outputs capable of transmitting either voltage or current signals to field devices.
The 1756-OF4 supports single-ended analog output operation and is commonly used for controlling variable frequency drives, control valves, actuators, and process instrumentation requiring stable analog reference signals. With 15-bit resolution and support for both ±10V DC and 0/4–20 mA output ranges, the module provides accurate signal conversion for demanding process control applications.
Designed for the ControlLogix platform, the module installs in a standard 1756 chassis and occupies a single slot within the rack architecture.
