Features
(1) High-reliable protection
The product includes a three-phase undervoltage and a three-phase overvoltage element.
It is used to detect abnormal voltage between lines.
(2) Communication Network
- With an open field bus system, the relays can be used to build a high-speed, high-performance
network system. In addition, the relay’s multi-drop serial wiring reduces the amount of labor
required for communication wiring.
- Control of measurement values, operation status, as well as setting changes, etc., can be
performed from a remote location.
- In consideration of future network system variations and compatibility with communication
networks, communication features are mounted in the relay using a replaceable card.
