Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1756SC-OF8H is an Allen-Bradley ControlLogix analog output module with HART protocol support, designed for installation in a 1756 ControlLogix chassis. It provides eight single-ended analog outputs, configurable for voltage or current, and enables digital communication with HART-equipped field devices. Typical applications include process control loops, distributed control systems, and diagnostic monitoring in industrial automation environments. Part number 1756SC-OF8H integrates into existing ControlLogix systems to add analog output and HART communication capability.
