UCTRONICS DC ±10V 0/4-20mA Current Voltage Signal Generator, USB Power Supply Interface Analog Simulator for PLC and Panel Debugging, Device Testing, Frequency Converter, Flow Valve

Simple easy to use

アナログ入力機器のオフセット・ゲイン設定には十分な性能4-20ｍA出力はデジタルテスターで0.03ｍｍ～0.23誤差なので範囲でしょう。 今までＨＩＯＫＩのアナログソース（11万相当）を使ってましたが遜色ありません。電源もUSBなので手軽。そして安価でお勧めです

I needed a way to simulate a 4-20mA signal, as from a piece of industial equipment. I needed it fast and my multimeter did not have this function (I know of others that do). I did have a little trouble figuring out where to connect the wires for simulating 4-20mA and then where to connect my wires to simulate 0-5vdc. But even with my very limited electronics experience and my (very) cheap (free) multimeter (from Harbor Freight), I was able to figure out the polarity and connections for 4-20mA and 0-5vdc. The manual was not real helpful to me, so I've included pictures labeling where I connected my wires. But I believe the Fluke multimeter that would simulate these test signals is several hundred dollars. In the meantime, this device works great. -T

Good quality product, delivered quickly, and exactly as described.

This simulator will do 0-10, 2-10 2-5, 0-3.3 Volts and 0-20, 4-20, 0-22 ma. It will display output value, percent of range or 0 to 50 HZ (not so useful in the US). It can be calibrated and the encoder steps can be adjusted. It is not likely to hold up to daily use in an industrial environment but for someone like myself that on occasion needs to simulate a transducer, it is perfect. I also purchased a micro usb to micro usb charging cable. I can use my phone to power the unit on the rare occasions that I need it without worrying about batteries or separate power supply.
