INPUT: pin 3-1 - 50-60Hz Input Res. = 6 kW/V (GALVANIC SEPARATION) - fig. 3 (For input voltage 500 Vac: max overload: 150%). OUTPUTS: (max error 1%). Voltage: pin 9-8: 0-10V (+ on pin 9) Load higher than 10kW. Current: pin 10-8 (current outgoing from pin 10) Load max: 500W Version 1: 4-20mA Version 2: 0-20mA Max error 1,5% (25°C) Vi > 1/10 of the range. VISUALIZATIONS ON : GREEN LED: supply on. INSTALLATION: see fig.3. (Wiring to an electrical board with a differential relay and a sectionalizing switch). The length of every wiring must be less than 30 m STEP RESPONSE (10%÷90%) < 360 msec SUPPLY: 2VA - 50-60Hz - Tolerance: ±10% Pin 5-6: 24 Vac or 230 Vac SIZE: 48x96x90 mm - undecal male base. Accessories available on request: E 171 : hooks for flush mounting. E 172 : undecal female base for DIN. M 13A: plexiglas protection IP 54-tight closure (for flush mounting).

FUNCTION The device measures the alternate voltage Vi at pins 1-3 and converts it into 0÷10Vdc and 4÷20mA (or 0÷20mA) outputs (voltage, current). Model A (fig.1) The operation field ranges from 0 to 100% of the nominal voltage. Model B (fig.2) The operation field ranges from 70% to 130% of Vi of the nominal voltage. USE It can be used for controlling the AC voltage.
