Product Overview

• Part No: 83SR04C-E, Alternative Code: GJR2390200R1411
• Brand: ABB

• Category: Binary Control Module83SR04C-E is a rack-mounted binary control module belonging to ABB Procontrol automation platform. It integrates local logic processing, digital signal acquisition and relay output functions. The module collects field switching status signals, executes binary control logic, and outputs drive signals to field actuators. It can independently realize group control and drive control loops, reducing the data load of the main controller. Adopting standard Eurocard plug-in structure, it is widely deployed in power plant auxiliary control systems and industrial process control equipment, serving as a critical spare component for system maintenance, renovation and expansion.
