The ABB GJR2370400R1040, also known as the SAFT 140 AOC, is a high-performance analog output card designed for the ABB SAFT 100 series of protection and control systems. This module provides four independent, galvanically isolated analog output channels, typically used to transmit control signals (e.g., 4-20 mA) to field devices such as actuators, valves, and variable speed drives. Engineered for reliability and precision in demanding industrial environments, the SAFT 140 AOC ensures stable and accurate process control. It is an essential component for integrating control systems with analog-controlled equipment in power generation, transmission, and other critical infrastructure applications.
