Convient set of accessories included. Review: This device is excellent for the money. - 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. ## Features - Power Supply: external connection micro USB-5V or external power DC 15-30V, each way makes the generator work, both ways also can be connected at the same time. Battery is not included. - Voltage Output: DC ±10V, precision is 0.01V, rotate the encoder knob to adjust output voltage, can be calibrated. - Current Output: 0-22mA, precision is 0.01mA, rotate the encoder knob to adjust output current, can be calibrated. - Multiple display: just push the small botton to switch the display mode between voltage and current, you can also follow the instructions to switch 0-100 percent or 0-50HZ display. - Product Dimension: 3.94” x 2.36” x 0.79” (100mm x 60mm x 20mm), portable and convenient. - Battery model: DC 3.7V 1000mAh 803040 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07L491RLM | | Best Sellers Rank | #93,150 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #27 in Function Generators | | Brand | UCTRONICS | | Brand Name | UCTRONICS | | Color | DC 4-20mA Signal Generator, No Battery | | Compatible Devices | PLCs, Panels, Frequency Converters, Flow Valves, USB-powered devices, DC-powered devices | | Customer Reviews | 4.4 out of 5 stars 279 Reviews | | Item Weight | 3.2 ounces | | Manufacturer | UCTRONICS | | Measurement Type | Multimeter | | Min.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It worked great for diagnostics on a 0-5vdc speed bias input. *by R***T on May 29, 2026* Great Diagnostic Tool at a Great Prics Directions are included and translation is not too difficult. Convient set of accessories included. ### ⭐⭐⭐⭐⭐ This device is excellent for the money. *by O***F on February 21, 2019* This simulator will do 0-10, 2-10 2-5, 0-3.3 Volts and 0-20, 4-20, 0-22 ma.

Here's how to add one. *by T***R on August 28, 2019* Works pretty well. Was off by about 10% when I got it but was able to get it calibrated pretty close after fiddling around with the instructions. It does NOT come with a built in battery and you need to power it externally. However, I took it apart and found a 2 pin connector for a lipo. I checked the charge voltage which was 4.25v which is on the high end for a 3.7v lipo. I picked up a small lipo pack and plugged it in and now I have an internal battery. It seems to charge off of the micro USB and it hasn't blown up in my face yet. I'd recommend keeping the instructions handy as it's not very straight forward when calibrating or going through settings. ## Frequently Bought Together - 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 - Adjustable 4-20mA Signal Generator Current Voltage Analog Simulator 0-10V/0-22mA Signal Sources for Value Adjusting PLC Controller Panel LED Testing Calibration - Jadeshay Current Loop, Two-Wire High Accuracy 4-20mA Current Loop Signal Generator LCD Transducer Test Signal Current --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nl/products/95406808-uctronics-dc-10v-0-4-20ma-current-voltage-signal-generator](https://www.desertcart.nl/products/95406808-uctronics-dc-10v-0-4-20ma-current-voltage-signal-generator) --- *Product available on Desertcart Netherlands* *Store origin: NL* *Last updated: 2026-07-22*
