Datasheet

T201 Series includes AC/DC current transducers designed to convert measured current value (up to 300 A) into a 4..20 mA or
0..10 V industrial normalized signal. T201 Series is UL certified and it is characterized by low power consumption, measuring
range freely settable via DIP-switches and high accuracy class avoiding thermal drift. T201 Series is available in 12 models
with different measuring principles: average rectified, magnetic balance (patented technology), Hall Effect or TRMS with bipolar
input range. Three models include an RS485 port supporting Modbus RTU protocol.

The Transducers that use the measurement based on magnetic induction technology are long life devices
thanks to the principle of measurement that avoids thermal drifts and which exploits the generation of an
induced current on the transducer output, through the variation of a magnetic field. A direct use will be
possible without any external shunts, even for pulsed currents.
When a magnetic field is applied perpendicularly to a conductor, a voltage is generated transversally to the
direction of the current flow.
The Hall Effect Current Transducers are used as alternative to shunt when dealing with high voltages and
high galvanic isolation.
