| The C-mac® module, type RV20 is a simple voltage monitoring relay for DC input signals. The module is available for several different metering ranges, but the range must be specified at ordering, since each unit has only got one metering range. By means of a connection at the relay base you can select, it the output relay should activate or release, when the setpoint is exceeded, in this way, the module can be used for both over- and under current monitoring.
