INPUT See Tab. A, other input voltages on request. Pin 8-4 (+4) Input resistance: 5KW/V Permanent overload: 200% (For input voltage 500 Vdc: max overload: 150%). OUTPUTS Voltage: pin 12-10: 0-10V (+ on pin 12). Load higher than 10KW Current: pin 11-9 (current outgoing from pin 11). Load max 500W. A : 4-20 mA B : 0-20 mA Max Error 1,5% (25°C) for input current > 1/10 of the range. VISUALIZATIONS ON GREEN LED: supply on. GALVANIC SEPARATION The input and output logic have different supply and are coupled by an optic coupler without frequency conversion. STEP RESPONSE: (10÷90%)< 4 msec. INSTALLATION: (wiring to an electrical board with a differential relay and a sectionalizing switch) see fig. 2. The length of every wiring must be less than 30 m. SUPPLY: 2,5VA - 50-60Hz Tolerance: ± 10% Pin 15-16: 230 Vac (or 24 Vac). SIZE: 47x75x115 mm – Din rail Accessories available on request: E 405D: transparent cover fitted for tight closure. IP protection class: 40. WEIGHT: 0,300 kg COLOUR: grey WORKING TEMPERATURE: 0÷70°C

FUNCTION The device measures the direct voltage and converts it into 0÷10Vdc and 4÷20mA (or 0÷20mA) outputs. Fig.1 shows the relation between the input current and the outputs (voltage, current). USE It can bee used for controlling the DC voltage.
