## Overview

The UCTRONICS DC ±10V 0/4-20mA Signal Generator is a compact, USB-powered analog simulator designed for professional PLC and panel debugging, device testing, and flow valve calibration. Featuring dual power inputs, ultra-precise voltage/current output, and a versatile multi-mode display, it delivers reliable, portable performance that elevates your electronics workflow.

## Description

UCTRONICS signal generator is designed to simulate 0-10V voltage signal and 0/4-20mA current signal for PLC and panel Debugging, Device Testing, Frequency Converter, Flow Valve, ect. Very easy to use, it can be connected with micro USB-5V power supply or DC 15-30V external power. What’s more, it can display 4 different types of digit,-10V-10V voltage, 0-22mA current, 0-100 percent and 0-50HZ. It will play a important role in your electronics work. This item does not include any battery inside.

Review: Simple easy to use
Review: 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

## Questions & Answers

**Q: Can i use this as a one pulse per second generator?  I don't see a way to adjust frequency**
A: Hi, this device is designed to simulate voltage and current signal, can't be used as a one pulse per second generator.

**Q: how do you install a battery?**
A: It does not come with a battery but you can buy a Lipo Rechargeable Lithium Polymer ion battery pack. The battery pack comes per-wired with the proper connector. Verify the connector pin polarity is correct before connecting. I just installed the YDL 3.7V 2800mAh 623360 (https://www.amazon.com/gp/product/B07BTRLKPT/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1) and it works fine. To disassemble

     1.  Ensure battery switch is in the OFF position.
     2.  Remove knob from dial encoder.
     3.  Remove nut from dial encoder.
     4.  Use small screwdriver to separate top from case (slots on one end to make this easy to do).
     5.  Remove 4 screws holding pcb in case
     6.  Remove pcb and flip over. Two pin JST connector on bottom for battery pack connection (polarity is marked)
     7.  Assuming polarity of battery pack connector matches pcb connector just plug the battery pack in.
     8.  Mound battery pack in case with double back tape or velcro pieces.
     9.  Reassemble in reverse order.
The unit should power up when battery switch is placed in ON position.

**Q: Can this output a current duty cycle?**
A: Not that I’ve found. Instructions a little sparse, Nicky made unit though, and reasonably accruate, certainly for the cost.

**Q: To the manufacturer...would you consider upgraded terminal block to the quality cam lever action terminal block instead of the screw block.**
A: If one is considering a high-current application, a Cam-Lever type terminal will not provide the compression needed over a wide area for a proper connection.

### ⭐⭐⭐⭐⭐ Review
*by T***E on 30 June 2019*

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
