| Monitoring Relays AC Current Transformer Types A 82-10, A 82-20 * 5 types of input: 0 - 25 AAC 0 - 50 AAC 0 - 100 AAC 0 - 250 AAC 0 - 500 AAC * Output: A 82-10: 0 - 20 mADC (source) A 82-20: 4 - 20 mADC (sink) * Easy interface to PLC or setpoint relays Product Description AC current metering transformer for 25, 50, 100, 250 or 500 AAC. Output current from the transformer is 0-20 mADC or 4-20 mADC in accordance with IEC 60381-1. Can be used with relays DIB01, PIB01, DIC01, PIC01 or S183 or directly connected to a PLC. Power supply ON is indicated by a green LED on the side of the housing.

This makes it very useful as an AC current interface to a PLC with mADC input. Used with relays DIB01, PIB01, DIC01, PIC01 or S183 one or more setpoints can monitor the current and signal alarm. S 183 also provides the DC voltage supply for the A 82-10, A 82-20. 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. A 82-10 has factory-set gain (span) adjustment, whereas A 82-20 has zero as well as gain (span) adjustment, both factory-set. Note: Do not change the set values. Wiring Diagrams A 82-10 ...
