4-Wire Current Transmitter
4-20 mA Output
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.
