FNIRSI SG-002 is a fully professional, multifunctional voltage and current signal generator for testing, diagnostics and commissioning of automation systems. It supports ±12V and 0-24 mA signals, operates in active and passive modes, with 2, 3 and 4-wire installations and is characterized by high accuracy after calibration (up to 0.05V / 0.05 mA). Thanks to its compact dimensions of 89×69×28mm, the FNIRSI SG-002 is a truly mobile signal source. It is a tool that effectively replaces several devices and provides complete signal control in any conditions.

Full compatibility with automation and PLC

The generator was designed with real industrial installations in mind. It works seamlessly with PLCs, inverters, proportional valves, converters and control systems. Support for both active and passive outputs allows you to test virtually any type of analog input - without any complications, additional resistors or external power supplies.

Universal voltage ranges - exactly what you need

The FNIRSI SG-002 offers a wide selection of voltage modes: ±12V, ±5V, 0–10V, 2–10V, 0–5V, 1–5V, 0–3.3V, 0–2.5V, 0–1V and –10–0V. This means that one device is sufficient for testing both classic industrial installations and modern electronics or low-voltage control systems.

Accurate current generation up to 24 mA

The current output covers a range of 0–24 mA and supports the popular 0–20 mA and 4–20 mA standards. Thanks to its high stability and accuracy after calibration, the generator is ideal for sensor simulation, analog input calibration and measurement circuit verification – even with loads up to 500 Ω.

Coarse and fine adjustment – full control over the details

The rotary encoder allows you to work in coarse and fine adjustment modes. This allows you to quickly set an approximate value and fine-tune it. One turn of the knob generates 30 pulses, which means very smooth and predictable adjustment – ideal for both quick tests and precise calibration.

Clear display and flexible presentation modes

The 4-digit LED display offers 8 brightness adjustment levels and various data presentation modes: actual value, percentage and special modes. This allows you to read the parameters quickly and unambiguously, regardless of the lighting conditions and the nature of the work.

Memory settings and quick start points

The generator allows you to save the set voltage or current values, which are automatically restored after a reboot. In addition, there is a quick start function that allows you to save several preset signal levels. This saves a lot of time during serial tests and repetitive maintenance procedures.

Three power supply options - ready to work anywhere

FNIRSI SG-002 can be powered from an external 15-30 V DC source (e.g. from a 24 V PLC installation), via a micro USB 5 V connector or from a built-in 1100 mAh / 3.7 V lithium battery. The device can operate while charging, which provides complete independence both in the field and in control cabinets.

Safe connection and logical terminal structure

Removable terminal strips allow for quick and safe connection of voltage and current signals. The well-thought-out terminal layout facilitates correct connection in active and passive mode and reduces the risk of errors when working in industrial installations.
