The CR4340 series, 4-Wire Current Transmitter pro-

duces a calibrated 4-20 mA DC signal proportional to

the average RMS value of the input alternating cur-

rent. 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 specifica-

tion 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.

... The "actual" measurement range will be the name plate range divided by the number of wire passes. For example, the CR4340-30 has the name plate range of 0-30 ACA. Two passes of the wire through the window opening will then provide an effective range of 0-15 ACA (30÷ ...
