## **Mode of Operation** 

The E 83-20 is a small AC current metering transformer with standardized 4-20 mADC output. This makes it very useful as an AC current interface to a PLC with 4-20 mADC input. 

or more setpoints can monitor the current and signal alarm. 

In the 5 A range the E 83-20 is often used as a 4-20 mADC signal converter for larger standard AC current transformers with 5 AAC secondary output. 

Used with relays DIB01, PIB01, DIC01 or PIC01, one

The metered conductor is drawn through the central hole of the current metering transformer. It is possible to measure 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 5 AAC when the current in the conductor is 1 AAC.
