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

Using a couple of these to simulate analog inputs on a PLC. Works perfectly. Have not tried the 0-10V functionality as 4-20mA is all I ever use. I really like that this device is in a plastic case. Everything feels solid! I do like that this is "hackable" to be used with a battery. I don't need this but it is nice to have the option. Wire this up to an M12 sensor cable and this can be used out in the field to test wiring as well. Good product and a solid buy if you need to simulate some analog sensors for programming.

Works as advertised, great way to check plc inputs, verify with a fluke 771, the output is accurate.

This is a nice tool, and inexpensive. It can be powered by a 24VDC power supply, or I used 2 9V batteries in series. There is one terminal for V-Out, one for I-Out, and one for A- Com. If you do not know what any of these terms mean, this is not the device for you. There are capabilities to edit patameter set for both current and voltage. Another reviewer posted snip of settings and procedure. I used these to get I-Out from a 4-20mA down to a 0-20mA output. Relatively small device, great for portability. Approximately 4" x 2" x 2" I will probably locate a hard case and line it with foam pad to store device.

I needed this to generate a 0-10volt analog control signal to test some ECM motors. It works perfectly. My only comment is that it should state that a 24volt DC input voltage is required. Fortunately the ECM motors I was testing required 24volts to power so I used the same transformer to power the signal generator. The LED display is also very useful and the fine adjustment is as well. A great little device for the price, if you need such a thing.
