General Specifications

 The T201 instrument is an AC current transducer

(CT) for 4 – 20 mA current loops (loop powered

2 wires technology).

 High precision.

 Extremely compact size.

 Wide configurability: eight pre-calibrated ranges,

DIP-switch selected.

 Extremely low consumption.

 Low output ripple and quick response to

variations.

 Damping filter (DIP-switches activable) to reduce

the response time (damping starts, unstable

loads, etc.).

0A Mounting The device can be located in any position and place, in accordance with the operating conditions above stated. Use the included holder bracket when fixing it to a DIN rail. WARNING: High-strength magnetic fields may change the output value. Avoid closeness to permanent magnets, electromagnets or iron bulks that cause such a modification of the surrounding magnetic field; try a different arrangement or orientation if zero error was greater than expected.
