MEASURING AND MONITORING RELAY FLARE CONTROL

Electronic measuring and monitoring relays for measuring input variables, such as current, voltage, phase, cos phi, temperature, and insulation resistance. Our flare CONTROL relays perform monitoring tasks in machines and systems.

The flare CONTROL relays are the ideal device for any monitoring task:

Voltage

Current
Phase sequence, phase errors
Temperature
Cos phi
They also have a wide temperature range and gold-plated switching contacts to guarantee high functional reliability.
