CT TRANSMITTER

(clamp-on current sensor)

Functions & Features

• Converts an alternating current into a standard process

signal

• Easy-to-install clamp-on type current sensor without

needing a current transformer

• Clamp-on current sensor included

• Wide input range from 10 A up to 600 A

• Input frequency 50 / 60 / 400 Hz

• Over-voltage clamp element for safety in open circuit

• LCD meter (engineering unit display selectable)

• Simple loop test output (0 % and 100 %)

• High-density mounting

Typical Applications

• Centralized monitoring and control of motors at a

supervisory panel

• Monitoring abnormal load current at motors to detect

pump malfunctions
