Emirel CS 12

INPUT Direct current: pin 3-5 (+on pin 3). Direct insertion up to 5A (Fig. 2). By means of an external shunt (60mV) for higher values fig.3 - see TAB.A. Permanent overload 150%. Voltage drop: 70mV MAX. OUTPUTS: (max error 1%) Current: ± 20mA (4-20mA not available). 250W max - pin 11-12 (current outgoing from pin 11). Voltage: ± 10 Vdc - pin 13-14(+on pin 13) load higher than 10kW. The outputs are positive when the input current is connected to pin 3. VISUALIZATIONS ON GREEN LED : supply on in the input section. ON YELLOW LED : supply on in the output section. GALVANIC SEPARATION The supplies of the input and output sections are given by two transformers. The two sections are optically isolated by a linear coupler without frequency conversion. Insulation: 4000 Vac between input and output for 1 minute. RESPONSE TIME: less than 20 micro sec. 10÷90% INSTALLATION: See fig.2. (Wiring to an electrical board with a differential relay and a sectionalizing switch). The length of every wiring must be less than 30m. SUPPLY 3VA- 50-60Hz Tolerance: ± 10% 7-8 : 115Vac or 230Vac or 24Vac INSTALLATION See fig.2 and fig.3. RANGES: see TAB. A. SIZE: 45x75x115 mm for DIN rail WORKING TEMPERATURE: 0÷70°C WEIGHT: 0,300 kg COLOUR: grey

FUNCTION The device measures the direct current at the input pins. Fig.1 shows the relation between the input voltage and the output current and voltage.
