RC10: Current monitoring RV10: Voltage monitoring 4 metering inputs in each module Adjustments for setpoint, hysteresis and time delay Selectable relay inversion, time delay 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 RC10, and voltage monitoring relay, type RV10, are universal metering relays, each supplied with 4 metering ranges, from 0,4 mA to 6 A or 40 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 is made by connection/disconnection of terminal 8 to common (terminal 7). By means of 2 push-buttons on the back of the unit you can select relay and time-delay function. 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.
