Type
Wattmeter relay
RELAY OUTPUT
The two internal relays RA and RB are “normally ON” (the
NC contacts are closed) and they will go “OFF” in case of
alarm.
ANALOG OUTPUT
At the pins 17-18 (+ on pin 17) the voltage 0-10Vdc full
scale (max 1mA) is available.
The 0-10 Vdc signal is proportional to the instant active
power Wa measured. It is suggested to apply a DC
VOLTMETER DVD 08, with calibration of the reading, in
order to display "100" or the value appearing on the
display of W 19 during normal operation (“A” screen).
INPUTS
Input Resistance = 800 k
Voltage pins: 15-13-11 (See Remark 3).
Maximum threephase voltage is 415 Vac.
For higher voltages is requested the application of M 08:
Threephase drop resistances (see Fig. 8).
In the W 19 set VN of the motor.
Ex. 480V Motor M 08 480/400 and in the W 19 set
VN=480V.
Current range: direct up to 80A, with external CT .../5 for
current higher than 80A. The use of CT with range 0.5 is
recommended.

FUNCTION
The device detects the absorbed current I, the three-phase
or single-phase voltage V, the cosφ and the active power
Wa absorbed by the motor.
USE
The electric motor is the typical load to be controlled by a
power monitor relay. In fact by monitoring the absorbed
power we get very accurate information about the load
applied to the motor.
Such information is more complete than the current
intensity. In fact the cosφ variations can generate power
variations, even in absence of remarkable variations of
current value.
