Description
Product Introduction
ABB RED670 1MRK004810-KG serves as a high-performance protection relay in the Relion 670 series. This IED delivers comprehensive transformer protection and control in substations and industrial power systems. Engineers use it daily for differential protection, backup protection, and integrated control functions.
The unit supports modern substation automation through IEC 61850 and maintains backward compatibility with existing ABB installations. This allows cost-effective upgrades without full system replacement while delivering precise fault detection and reliable tripping.
Frequently Asked Questions
Q: Does the RED670 support hot-swapping? A: No. In our experience, these protection IEDs require the system to be de-energized before replacement. The hardware design does not support live module exchange due to power and communication bus constraints.
Q: Is this model obsolete and what are the direct replacements? A: The RED670 series has reached end-of-life status at ABB. Most sites migrate to the REL670 or newer 670 series successors. Record your exact firmware version before any swap and confirm mapping of function blocks.
Q: Will I lose my existing program and settings during replacement? A: You should not lose the configuration if you extract the parameter file first via PCM600. Always back up the full project and compare settings after installation. The most common mistake is skipping this step.
Q: Are these factory-new or refurbished units? A: These are new original surplus units. We source them from authorized channels with full traceability. Every unit undergoes our inbound inspection, functional testing on a relay test set, and 24-hour burn-in before shipment.
Q: What warranty coverage and lead times apply? A: We provide a 12-month operational warranty from shipment. Most units ship within 1-3 business days from our stock. Verify power supply rating and I/O configuration match your application before ordering.
Q: Any critical pitfalls when installing this module? A: Photograph the DIP switches and jumpers on the old unit before removal. Also confirm bus termination resistors remain correct. Adding multiple communication boards can exceed the 20 percent power supply margin we recommend leaving. Always use an anti-static wrist strap.
