RC12/RV12, current and voltage relays - 1

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.
