W2CE CURRENT TRANSMITTER
(RMS sensing)

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

MODEL: W2CE–[1][2][3]-[4][5]

ORDERING INFORMATION
• Code number: W2CE-[1][2][3]-[4][5]
Specify a code from below for each [1] through [5].
(e.g. W2CE-5AA-M2/CE/Q)
