Programmable 4-20mA Current Signal Generator Simulator
BRT 420G-HM3 4-20mA Current source generator is a low error, high accuracy stable current signal calibration meter,
it designed by following industrial standards. Inside the signal generator, there are large power MOS tube, high
precision power chips, high speed CPU IC, precision AD chips, current loop circuits, all these make that signal
generator much more stable and accurately.
Main Features
 0.5% accuracy grade, high linearity output.
 Using long life span encoder with stepless knob, can rotate and press it.
 Have two types of adjusting mode: rough adjustment and fine adjustment.
 Fine adjustment can be 0.01mA/pulse, rough adjustment can be 5mA/pulse.
 Programmable output, output range can be set into 0-20mA, 4-20mA, 0-22mA
 LED display is settable among current signal value display, 0-100.0 percentage display, etc.
 Min. Changing step can be 0.01mA (the last digit plus or minus 1)
 4 digits 0.4-inch clear LED display, standard panel-mounted package.
 4 Pin pluggable wiring terminal blocks, easy to do wire connection.
 Output has short-circuited protection functions.
 Have polarity reverse connection protection circuit in power supply terminals.
 Digital encoder used, long durability, strong anti-interference capability.
