RC15: AC-current monitor RC20: DC-current monitor Adjustment of setpoint and hysteresis Selectable activation or release of relay DC supply or AC supplies up to 230 VAC 1- or 2-pole relay output Made in accordance with the and EMC regulations The C-mac® modules, type RC15 and RC20 are simple current monitoring relays, for AC- and DC input signals, respectively. The modules are 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.
