Designed for precise PLC panel and LED testing, it features a multi-cycle potentiometer for fine-tuning, operates on 24VDC or battery power, and is validated for accuracy, making it an indispensable tool for industrial troubleshooting and calibration. ## Description Product description By rotating a multi-cycle precise potentiometer, DROK Amp & Volt Dual Signal Generator can easily generate 0-10V voltage signal and 0/4-20mA current signal. The versatile generator can be widely used as signal generator, value generator, value adjustment, inverter control, PLC debugging, panel debugging, LED testing, simulating the output of transimitter. PRODUCT SPECIFICATIONS Product Parameters Working voltage: DC24V Input signal: Potentiometer Output signal: 0/4-20mA or 0-10V Display accuracy: Current: 0.1mA; Voltage: 0.01V Dimension: 100*68*38mm Package Includes 1* Signal Generator WIRING INSTRUCTION "24V" --- Power Supply + "0V" --- Power Supply - "0V" --- Signal Output - "0-20mA" --- Current Output + "0-10V" --- Voltage Output + DEBUGGING PROCEDURES A. Current display calibration Clockwise rotating the multi-cycle potentiometer to the maximum, switching the display switch to the right and then using a multimeter to test the actual value of the output current. At this time, you can adjust the current display adjusting potentiometer to make the display value equal to the actual output value. B. Voltage display calibration Clockwise rotating the multi-cycle potentiometer to the maximum, switching the display switch to the left and then using a multimeter to test the actual value of the output voltage. At this time, you can adjust the voltage display adjusting potentiometer to make the display value equal to the actual output value. ## Features - AMP & VOLT DUAL SIGNAL GENERATOR: Multifunctional DROK signal generator kit is able to generate ampere & voltage by 1 module, which generate 0/4 - 20mA current signal and 0-10V voltage signal just by rotating a multi-cycle precise potentiometer, simple and handy. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.3 out of 5 stars 529 Reviews | ## Images ![DROK 4-20mA Signal Generator - Image 1](https://m.media-amazon.com/images/I/71mN-1PgKJL.jpg) ![DROK 4-20mA Signal Generator - Image 2](https://m.media-amazon.com/images/I/711OheWExRL.jpg) ![DROK 4-20mA Signal Generator - Image 3](https://m.media-amazon.com/images/I/71CIuBz-ZaL.jpg) ![DROK 4-20mA Signal Generator - Image 4](https://m.media-amazon.com/images/I/61m+D39KvRL.jpg) ![DROK 4-20mA Signal Generator - Image 5](https://m.media-amazon.com/images/I/71YmgajbeTL.jpg) ## Available Options This product comes in different **Number Of Items** options. ## Questions & Answers **Q: how long will it run on 2 9 volt batteries?** A: That will depend very much on the use you make of it; we have used the same batteries for several weeks now, but the use is intermittent and for testing or commissioning only. **Q: Can someone please give a detailed explanation of how to use and generate a signal with this device?** A: This is used to simulate either a 4-20ma or 0-10vDC signal in a test environment, selectable via on board switch. I have found that depending on the input resistance of your load using 9 volt batteries in series may not have enough capacity so I use a small 24vDC power supply to power the generator. Connect your generator power wires & appropriate output wires observing the correct polarity & you should be fine **Q: I see there is a place on the pc board for an on off switch. can this be added?** A: Not sure. When power is applied to the terminals, the meter comes alive. Not sure if the printed circuit card pads will turn off the meter, as I do not see any jumper or other means that is completing the circuit. I am just disconnecting the power to turn the meter off. **Q: When providing power to this product, what is the input voltage? does it accept a vdc voltage range?** A: The input voltage to this device is 24VDC, and have an analog output 0-10Vdc or 0-20mA. Works really good. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***L on January 14, 2026* ### ⭐⭐⭐⭐⭐ Review *by T***D on September 13, 2023* ### ⭐⭐⭐⭐ Review *by W***A on July 6, 2019* ## Frequently Bought Together - DROK 4-20mA Generator, Adjustable Signal Generator, DC 0-10V 0 4-20mA Current Voltage Analog Simulator for Value Adjusting PLC Panel LED Testing - Adjustable 4-20mA Signal Generator Current Voltage Analog Simulator 0-10V/0-22mA Signal Sources for Value Adjusting PLC Controller Panel LED Testing Calibration - Riiai Upgraded 4-20mA 0-24V Current Signal Generator, Current Voltage Adjustable Analog Simulator, Real-time Curve, Multiple Signal Types, 3000mAh USB Rechargeable, Preset Value, for PLC Testing --- ## 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.com.cy/products/45049867-drok-4-20ma-signal-generator](https://www.desertcart.com.cy/products/45049867-drok-4-20ma-signal-generator) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-05-05*
