The current-voltage analog simulator is designed to automatically display the changing trend of input and output signals by the real-time curve, and the sampling time of the curve can be set. Compared with the 003 model, it supports recording and viewing a certain amount of historical data in an easier way - Multiple Interface Terminals：The 0 to 24V DC signal generator kit adopts 4 inner diameters and 4mm wiring ports on the top surface that are represented by different color rings. The Blue port (IN-) is an alternate function, and it is also an input that can be switched to a 24V independent test power supply. The Red (OUT) port and Black (COM) port form an output port. Yellow (IN+) and Blue(IN-) form the input port. Users can choose the correct color cables and ports to start testing - 3000 mAh USB Rechargeable & TFT Screen： With a 3000mAh 3.7V USB rechargeable battery (charged via a micro 5V USB port, the adapter is not included), the thermocouple calibrator can be fully charged within 4-6 hours, with a working time of up to 26 hours. It takes longer time to use and makes it easier to know the value changes through the clear 2.4-inch TFT screen display, and users can adjust the screen backlight according to the field - Programmable Output & Wide Application： The 0 24v DC 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. 4 groups of commonly used signal values can be preset to facilitate quick adjustment of output. It is widely used for PLC and panel debugging, device testing, frequency converter, flow valve, servo motors speed regulation, light dimmer, etc ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B8V811G6 | | Best Sellers Rank | #32,926 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #3 in Function Generators | | Brand Name | Riiai | | Color | Blue | | Compatible Devices | PLC, frequency converter, flow valve, servo motor, light dimmer | | Customer Reviews | 4.2 4.2 out of 5 stars (16) | | Item Dimensions | 4.41 x 3.23 x 1.06 inches | | Item Weight | 165 g | | Manufacturer | Riiai | | Measurement Type | Ammeter, Voltmeter, Ohmmeter | | Model | SG004 | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | LSYUS51ZHP0029 | | Power Source | Battery Powered | | Style Name | fashion | | Unit Count | 1 Count | ## Product Details - **Brand:** Riiai - **Color:** Blue - **Item Weight:** 165 g - **Power Source:** Battery Powered - **Style:** fashion ## Images ![SG004A 4-20ma 0-24V Signal Generator, Programmable Current Voltage Generator, Resistance Millivolt Thermocouple Tester, Real-time Curve, 3000mAh USB Rechargeable, for PLC Simulator - Image 1](https://m.media-amazon.com/images/I/71pNtGyBb+L.jpg) ## Available Options This product comes in different **Model** options. ## Frequently Bought Together - Riiai 4 20ma 0 24V Signal Generator, Programmable Current Voltage Generator, Resistance Millivolt Thermocouple Tester, Real-time Curve, Historical Record, 3000mAh USB Rechargeable, for PLC Simulator - 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.at/products/474164897-sg004a-4-20ma-0-24v-signal-generator-programmable-current-voltage](https://www.desertcart.at/products/474164897-sg004a-4-20ma-0-24v-signal-generator-programmable-current-voltage) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-10-22*
