Adjustable 4-20mA Signal Generator Current Voltage Analog Simulator 0-10V/0-22mA Signal Sources for Value Adjusting PLC Controller Panel LED Testing Calibration: desertcart.com: Industrial & Scientific

Review: Good Value and Simple to Use - SImple to use. Battery was charged when I received so I was able to play with it right away. Also has capability to run off 24VDC power or USB adapter (comes w/cord but you'll need the USB power supply/phone charger) Good value; I'm not looking for a calibration quality device so it fit my needs. I will be using it as a 4-20mA source. It outputs at 24VDC in the mA generator mode. It was accurate enough for what I will be using it, mainly troubleshooting or modeling. I don't need to be highly precise. I noticed the signal bounced somewhat, but it was in the magnitude of .01's. This difference just as well could be from the precision of the controller/PLC that I was connected to. Comes with a USB power cord and little tweaker screwdriver. Nice to have when you are working in the field.
Review: Works great! - This is awesome for testing systems. It's small and light as well, so easy to carry with commissioning tools. Great price as well. I don't need it for calibration, just to similate and trouble-shooting.

### ⭐⭐⭐⭐ Cost effective 4-20 ma simulator
*by 1***R on January 23, 2025*

Works reasonably well. Bought 8 of these for testing analog inputs on panels. Like the ability to simulate both passive and active 4-20 ma circuits and the adjustable knob rate. Battery lasts 30 - 60 minutes in the modes we use them in. We use these with a USB power strip and just plug them all in. USB cords that ship with the units are short, ordered longer ones. Devices tend to lock up every couple of days, just power cycle them to clear. Instructions aren't clear but what else is new. Not too hard to figure out.
