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
