It is a 4-20mA Signal Source Signal Generator, Power supply: DC12 ~ 30V, The product can be used: signal source, valve adjustment, inverter control, PLC debugging, instrumentation test, analog transmitter output.

• Multi-ring (5 * 360) potentiometer knob operation, stepless fine adjustment,in response to the output immediately,no delay
• Potentiometer to adjust the actual fineness of up to 0.01 mA
• Power supply: DC12 ~ 30V,DC 12V or 24V, current 18mA, power port has a polarity protection, power reverse does not work, do not burn components.
• 4-bit 0.36-inch LED, the display range: -1999 ~ 9999, can be set to the number of  0,1,2,3 decimal points
• 20mA output: the maximum output current of 24mA.
• 12V DC power supply: output load impedance range between 0-350 ohms
• 24V DC power supply:output load impedance range between 0-800 Ohms
• The test output is normal, you can use a multimeter (DC current file) short "4-20mA output" terminal value and the comparison shows that the multimeter readings are the same.
• Easy to install, standard 7943 shell, panel size: 79mm * 43mm * 25mm,hole size: 76.5mm * 39.2mm
• The product can be used: signal source, valve adjustment, inverter control, PLC debugging, instrumentation test, analog transmitter output.

• If the menu requires a password, the default password is 1234, flashing display.
• Such as, if it is used to control a device for -90 degrees to +90 degrees action.
• The default display is Current.
• It can also be redefined as: 4mA display -90.00, 20mA display +90.00 (2 decimal point), this can be displayed as 4-20mA -90.00 to 90.00 (2 decimal point).

• 1 x 4-20mA Signal Source Signal Generator
