Product Introduction
ABB REG670 4200195301-01C is a turbine control and protection module for gas and steam turbines, part of ABB’s REG 670 series. It manages turbine speed, load sharing, and protective tripping while integrating with plant DCS for real-time control. This module is widely used in power generation plants requiring deterministic control and reliable protection functions.
It supports Modbus RTU and Profibus DP communications, allowing backward compatibility with existing REG 670 CPUs. The unit’s analog and digital I/O configuration offers flexible integration with sensors and actuators. Verified firmware ensures proper functionality, and New Surplus units are fully tested, including load simulation and electrical verification, to minimize installation risk.
Frequently Asked Questions
Q: Can I hot-swap the REG670 4200195301-01C?
A: No. This module must be powered down before replacement. Hot-swapping risks bus communication errors and may damage analog circuits.
Q: Is this module obsolete?
A: It is a legacy 670 series module, but still supported. Firmware Rev mismatch with older CPUs is common. Always record the existing CPU firmware before installation.
Q: Will I lose my program during replacement?
A: Possibly. Export configuration, record DIP switch settings, and note bus termination parameters to ensure full restoration.
Q: Are these factory-new or refurbished?
A: New Surplus. Each unit undergoes inbound inspection, full functional testing (>24-hour load test), electrical insulation testing, firmware verification, and anti-static packaging.
Q: Recommended power supply margin?
A: Leave 20% extra capacity on the 24 VDC supply to accommodate module additions and prevent brownouts.
