Functions & Features

• Converting an alternating current from a current

transformer into a standard process signal

• Wide range of frequency can be accepted thanks to the

incoporated wide-range CT

• Isolation up to 2000 V AC

• High-density mounting

Typical Applications

• Monitoring load current of motors employing inverters

• Detecting failures of a pump or other device by monitoring

abnormal load current of motors
