## Summary description

The Fnirsi SG-002 is a versatile multifunctional signal generator designed for precise electronic testing and calibration. This compact device supports various signal output types, making it an essential tool for engineers and technicians working with industrial automation, laboratory equipment, and electronic circuit debugging. Its intuitive interface ensures reliable performance for signal simulation and troubleshooting tasks.

## Long description

The Fnirsi SG-002 is a professional, multifunctional voltage and current signal generator engineered for the testing, diagnostics, and commissioning of industrial automation systems. This compact device serves as a versatile signal source, capable of handling ±12 V and 0–24 mA signals while supporting both active and passive operating modes. With its ability to interface with 2-, 3-, and 4-wire installations and high calibration accuracy, it provides reliable control for various electronic environments.
Advantages
The device offers exceptional flexibility by supporting a wide range of voltage and current standards, including common industrial 0–20 mA and 4–20 mA loops. Its dual-mode adjustment system, featuring a high-precision rotary encoder, allows for both coarse and fine tuning, ensuring exact signal output. The integrated 4-digit LED display with adjustable brightness ensures clear visibility in any lighting condition. Furthermore, the device is highly portable, featuring three distinct power supply options, including a built-in lithium battery, which allows for continuous operation even while charging.
Suitable for
Testing and commissioning of PLC systems
Calibration of sensors and transducers
Debugging of industrial control loops and proportional valves
Laboratory research and electronic circuit development
Field service and maintenance of automation equipment
This device may not be suitable for high-voltage power applications or tasks requiring signal generation beyond the specified ±12 V and 24 mA ranges. It is intended for low-voltage signal simulation and testing rather than power supply or high-current industrial driving applications.
Key specifications
Voltage output range: ±12 V with multiple selectable modes
Current output range: 0–24 mA
Accuracy: ±0.05 V and ±0.05 mA after calibration
Load resistance: Up to 500 Ω for current output
Power options: 15–30 V DC, 5 V micro USB, or 1100 mAh internal battery
Dimensions: 89 × 69 × 28 mm
Adjustment: Rotary encoder with 30 pulses per revolution
To use the Fnirsi SG-002, connect your target device to the detachable terminal strips, ensuring the correct wiring configuration for active or passive mode. Use the rotary encoder to select the desired voltage or current output. You can toggle between coarse and fine adjustment modes to achieve the precise value required. The device automatically saves your settings, allowing for quick restoration upon restart. Use the display menu to switch between actual value and percentage modes as needed for your specific application.
What to consider before purchase
Verify that your application requirements fall within the ±12 V and 24 mA output limits.
Ensure the device's wiring compatibility matches your existing 2-, 3-, or 4-wire systems.
Consider the need for portability versus fixed laboratory use when selecting power methods.
Usage recommendations: For optimal accuracy, perform a calibration of the device periodically, especially when switching between different load environments. Always ensure the terminal strips are securely connected before powering on the unit to prevent signal instability.
