M2CA

Super-mini Signal Conditioners Mini-M Series

CT TRANSMITTER
(Average sensing, RMS calibrated)

Functions & Features
• Converts alternating current from a current transformer into a standard process signal
• Minimum ripple
• Rerouted input signal does not pass through the base socket in order to protect it from melting caused by rush current of a motor
• CT Protector provided for open-circuit protection
Typical Applications
• Centralized monitoring and control of motors, pumps or heaters by DCS
• Monitoring power line and power supply current
