A82-30250 Carlo Gavazzi

A82-30250, Monitoring Relays True RMS AC Current Transformer Types A 82-10, A 82-20, A 82-30, A82-30250, True RMS AC current metering transformer for 25, 50, 100, 250 or 500 AAC. Output current in accordance with IEC 60381-1 (A 82-10, A 82-20) or output voltage in accordance with IEC 60381-2 (A 82-30). A 82-10 and A 82-20 can be used with relays DIB01, PIB01, DIC01 or PIC01. A 82-30 can be used with DUB01, PUB01, DUB71, DUC01 or PUC01. All units can be directly connected to a PLC. Power supply ON is indicated by a green LED on the side of the housing., A82-30250, A 82-10 and A 82-20 are true RMS current metering transformers with standard source/sink output 0-20 mA / 4-20 mA, whereas A 82-30 is a metering tranformer with 0-10 VDC output voltage. This makes them very useful as an AC current interface to a PLC with mADC or VDC input. Used with relays DIB01, PIB01, DIC01, PIC01 (A 82-10, A 82-20) or DUB01, PUB01, DUB71, DUC01, PUC01 (A 82-30), one or more setpoints can monitor the current and signal alarm. The metered conductor is drawn through the central hole of the current metering transformer. It is possible to meter currents below the nominal range by drawing the conductor through the hole several times. If the conductor is drawn through the central hole e.g. 5 times, the transformer will register 50 A when the current in the conductor is 10 A.
