2-Wire Current Transmitter, 4-20 mA Output
The
CR4320
series, loop-powered, 2-Wire Current Transmitter produces a calibrated 4-20 mA. DC output current directly proportional to the average RMS value of the input alternating current. The controlled current output is unaffected by variations in supply voltage, interconnect and load impedance (within specification limits) to provide a highly accu- rate means for monitoring alternating current over long distances.
