Description
BRT 420G-HM3 Intelligent adjustable 0-20mA 4-20mA current signal generator simulator is a low error, accurate reliable programmable current source signal simulator debugging meter, it is 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 this signal generator much more stable and accurately.
Main Features
•0.01mA error, high linearity output.
•Output range is switchable: 0-20mA, 4-20mA, 0-22mA, 0-24mA. Switching via knob.
•Using long life span encoder with step-less knob, can rotate and press it.
•Fine adjustment can be 0.01mA/pulse, rough adjustment can be 5mA/pulse.
•Programmable adjusting mode: rough adjustment or fine adjustment.
•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-circuit protection functions.
•Have polarity reverse connection protection circuit in power supply terminals.
•Digital encoder used, long durability, strong anti-interference capability.
