What is a DC Power Relay?
DC Power Relay Definition
This is a relay that performs high-voltage and high-capacity urgent shutdown of DC circuits.
These relays not only energize DC circuit but also shutdown the high voltage circuit at high speed when an error occurs.
DC Power Relay Features
Omron's DC power switching technique contributes to space saving, noise reduction, miniaturization, and power saving, and is characterized by a safety and reliability design.
