DROK 4-20mA Generator, Adjustable Signal Generator, DC 0-10V 0 4-20mA Current Voltage Analog Simulator for Value Adjusting PLC Panel LED Testing








Key features
- •AMP & VOLT DUAL SIGNAL GENERATOR: Multifunctional DROK signal generator kit is able to generate ampere & voltage by one module, which generate 0/4 - 20mA current signal and 0-10V voltage signal just by rotating a multi-cycle precise potentiometer, simple and handy.
- •CLEAR LED DISPLAY: Our generator has bright and clear 3-digit LED digital display screen, which can be used to monitor the output current and voltage. You just need to push the switch below the monitor easy to switch the display.
- •AMP & VOLT DISPLAY CALIBRATION: There are current and voltage display calibrating potentiometer on the back of the module. If the display is accurate, you can calibrate the display value of current voltage by yourself.
- •WIDE APPLICATION: Our signal adapter can be used as signal generator, valve adjustment, inverter control, PLC debugging, panel debugging, LED testing, simulating the output of transmitter.

Great entry level signal generator
Tool Junkie•May 15, 2018
It's bare bones but does everything I need and the price can't be beat. There is no documentation, either online or printed, however you don't need to be a rocket scientist to figure it out. I also like that it does 0-10vDC as well as 4-20ma
Useful, does what it says

Useful, does what it says, but would be better if it had an on/off switch. I glued 2 magnets to the sides for a pair of 9v batteries to power it at 18v. Perfect for setting valve positions during commissioning or replacement, and testing damper motors in economizers.
Five Stars

Really nice product
Good signal generator for PLC training
Scott W. Vincent•March 25, 2018
I bought this to supplement my learning of PLC Programming. I have a Micrologix 1100 which has two analog inputs that accept a 0-10v signal, and this unit fit the bill. I tested it with a digital multimeter first and overall the display is fairly accurate, certainly good enough for the price. Connected to the PLC, it does exactly what I need. I also tested the 0-20mA output and sure enough, it works also. I'm sure if I continue with PLCs I'll find more uses for it. It's good for the price!
Very good value!

So far this unit has performed very well. I checked the accuracy right out of the box with my Fluke 87 and it was right on! It does have a way to adjust both the voltage and milliamp output on the back of the board. I also put 2 - 9 volt batteries in series for the power supply and they fit inside the box. The PC board also has a pin out for a power switch which I added to turn off when not in use. I have used it for a week now, I experiment with vfd's and other analog control devices and then put together installation and programming instructions. This is as good as any signal generator out there!
