INPUT Direct current: pin 3-1 (+on pin 1). Direct insertion (Fig. 2): Tab. A. By means of an external shunt (60mV) fig.3: Tab. B. Permanent overload 150%. Voltage drop: 70mV MAX. OUTPUTS: (max error 1%) Current: 4-20mA or 0-20mA. R max = 500W - pin 10-8 (current outgoing from pin 10). Voltage: 0-10Vdc - pin 9-8 (+ on pin 9) load higher than 10kW. VISUALIZATIONS ON GREEN LED: supply on. INSTALLATION: see fig. 2 and 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. GALVANIC SEPARATION The supplies of the input and output sections are given by two secondaries of the transformer. The two sections are optically isolated by a linear coupler without frequency conversion. STEP RESPONSE (10%÷90%) < 200 msec SUPPLY 2VA- 50-60Hz - Tolerance: ± 10% Pin: 5-6: 24 Vac or 230 Vac RANGES: see Tab. A and Tab. B (external Shunt on request). 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). E 346: spring protecting from vibrations. Template: 45x92 mm. WEIGHT: 0,230 kg COLOUR: black WORKING TEMPERATURE: 0÷70°C

FUNCTION The device measures the direct current and converts it into 0÷10Vdc and 4÷20mA (or 0÷20mA) outputs. See Fig. 1. USE It can be used for controlling the DC current.
