The CM-UFD.M22M is a multifunctional grid feed-in monitoring relay with an integrated Modbus RTU interface. It monitors the mains values required by CEI 0-21, such as over- or undervoltage (10-minute average, voltage reduction and increase protection) as well as all changes in the grid frequency (frequency increase and decrease protection). In addition, a ROCOF function (frequency gradient monitoring) can be activated.
