Product Introduction
ABB REG670 1MRK002826-AC is a dedicated turbine control and protection module for gas and steam turbines. It regulates turbine speed, manages load sharing, and executes protective trips, integrating tightly with ABB 670 series DCS systems. Its combination of analog and digital I/O enables precise interfacing with sensors, actuators, and other plant control equipment.
The module communicates via Modbus RTU or Profibus DP, supporting backward compatibility with legacy 670 CPUs. Firmware verification ensures reliable operation and reduces the risk of integration errors. New Surplus units undergo strict testing—including power-on self-test, full-scale I/O simulation, load testing over 24 hours, insulation measurement, and anti-static packaging—so installation risk is minimized.
