The input signal can be converted into an output signal among different physical quantities - 【2.4 Inch TFT Colorful Screen】 Designed with an adjustable pressing button backlight and a high-definition 240*320 TFT color LCD screen, it makes the signal generator kit for PLC testing easier for users to operate at night and during the day - 【Built-in 3000 mAh USB Rechargeable】 With a 3000 mAh 3.7V built-in USB rechargeable battery embedded inside (charged via a micro 5V USB port), the function generator can be fully charged within 4-6 hours. Its working length of up to 26 hours allows for a longer working period - 【Multiple Interfaces to Choose】 Main interface programmable output. Input waveform interface: switchable input current graph display, input voltage graph display. VCA conversion interface: switchable voltage to active current, voltage to passive current, current to voltage. Automatic interface: automatic mode can be set for single ascent, single drop, and loop. PWM interface: Output PWM signal, voltage, frequency, and duty cycle can be set - 【Programmable Output】 The 4-20 ma signal generator has the output function of auto, continuously changes the size according to the set parameters, and chooses three modes: monotonous rise, monotonous fall, and cycle ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B425J18L | | Batteries | 1 Lithium Ion batteries required.

If the two outputs are connected together, it is easy to burn the controller. The wiring is different to protect the controller from burning. **Q: What signal types can the 4 20ma signal generator support?** A: Dear Customers, Compared with Riiai 003 signal generator, Riiai 004 type 4 20 ma calibrator is upgraded to support switching various signal modes available under different signal types: mA Current Signal(0 to 24 mA, resolution 0.001mA), V Voltage Signal(0 to 24V, resolution 0.001V), XMT Passive Current Signal(0 to 24mA,resolution 0.001mA), Hz Pulse Signal(Frequency Output 0 to 9999Hz, resolution 5 digits), Resistance (0-390Ω, resolution 0.1Ω) Millivolt(-10-100mv, resolution 0.01mv). The functional generator can be applied to more tests. There is also a video for your reference. **Q: What's the difference between Riiai 003 signal generator and 004 function generator?** A: Dear Customers, Compared with 003 model(Blue type), the 004 model 4 20 ma signal generator is upgraded to support thermocouple testing, paperless history record that has a wider range of use. The rest functions are almost the same as the 003 model. Hope it helps. **Q: Where can i get english firmware? mine is in chinese.** A: Hi Jason, please contact us at support@riiai.com to get English firmware. ## Frequently Bought Together - 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 - Adjustable 4-20mA Signal Generator Current Voltage Analog Simulator 0-10V/0-22mA Signal Sources for Value Adjusting PLC Controller Panel LED Testing Calibration - DROK 4-20mA Generator, Adjustable Signal Generator, DC 0-10V 0 4-20mA Current Voltage Analog Simulator for Value Adjusting PLC Panel LED 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.tn/products/455327627-riiai-sg003a-4-20ma-0-24v-current-signal-generator-current](https://www.desertcart.tn/products/455327627-riiai-sg003a-4-20ma-0-24v-current-signal-generator-current) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-06*
