Current/voltage relays RC12/RV12
RC12: Current monitoring
RV12: Voltage monitoring
3 metering inputs in each module
Adjustments for setpoint and hysteresis
Selectable relay inversion and AC/DC mode
DC supply or AC supplies up to 230 VAC
Made in accordance with the
and EMC regulations
C-mac® current monitoring relay, type RC12, and
voltage monitoring relay, type RV12, are universal
metering relays, each supplied with 3 metering
ranges, from 4 mA to 6 A or 400 mV to 600 V AC or
DC, respectively.
The input range is chosen by use of the appropriate input terminal, and the choice of AC/DC metering and
relay inversionis made by connection/disconnection
of terminal 5 and 8 to common (terminal 7).
When the module is AC metering, the average value is
metered, and the level adjustment is then calibrated to
the r.m.s. value of a sinusoidal signal.
