T22CT

-AC TrAnsduCer

T22CT a transducer for measurement of AC current. It provides 4 to 20 mA or 0 to 20mA dC output.

It can be used for:

• For network analysis, monitoring,

• Measuring of non -sinusoidal and distorted networks.

Features:

• MeasurementofACcurrentforfrequency50/60Hz,Providesproportional4-20mAor0-20mAdC output.

• High electric isolation between primary conductor and output.

• easy and safety electrical connection by means of spring clamp terminal.

• direct mounting onto the bus bar by means of integrated fixing screws which are part of the unit.

• Mounting onto 35 mm dIn rail by means of optional supply of snap on mounting.
