Introduction

The CR4340 series, 4-Wire Current Transmitter produces a calibrated 4 - 20 mA DC signal proportional to the average RMS value of the input alternating current. The output signal is produced by an internal current generator powered from an external 120 Vac supply. The output signal is unaffected by variations in interconnect and load impedance (within specification limits) thus providing a highly accurate means for monitoring alternating current over long distances. The 4-wire transmitter allows for direct attachment to instrumentation. There is no need for external DC power as required with 2-wire transmitters.

Features

• Permanently calibrated
• Fully isolated
• Output overload protected
• 13 different ranges - 6 field selectable
• Internal current generator
• 2 case styles, .94” (23.9) and 2.13” (54.1) window opening
• Monitors over long distances

Applications

• An external current transformer may be used with the transmitter by routing the secondary leads through the window opening.
• The scaling factor may be changed by threading the primary current - carrying wire several times through the window opening.
