4-20mA signals are popular and have multiple uses. But testing and generating them from microcontrollers/PLC is difficult and required complex circuits. This module can be used to generate a 4-20mA current signal. It comes with a knob to vary the signal and a display to view the current signal value. Usefull for simulating sensor signals, testing 4-20ma circuits, calibrating microcontroller/PLC ADCs, etc.
This 4-20mA signal generator is a precision adjustable panel-mounted 4-20mA current loop simulator or signal generator with an LCD display.
Its output range is switchable between default 4-20mA and max. The LCD screen has a backlight for different light conditions. Its current signal display modes and adjusting steps can be set through the knob. This low-cost 4-20mA loop simulator also can output curves preset dynamically. It is ideal to use in meter, sensor signal testing, PLC, DCS and other instruments signal debugging, etc.
