FNIRSI SG-002 Multifunctional Signal Generator

The FNIRSI SG-002 is a professional multifunctional signal generator designed for testing, diagnostics, and commissioning of automation systems. It supports ±12 V and 0–24 mA signals, operates in active and passive modes, and works with 2-, 3-, and 4-wire installations. With high accuracy after calibration (up to 0.05 V / 0.05 mA) and a compact size of 89 × 69 × 28 mm, it is a truly mobile signal source.

• Wide voltage ranges: ±12 V, ±5 V, 0–10 V, 2–10 V, 0–5 V, 1–5 V, 0–3.3 V, 0–2.5 V, 0–1 V, and –10–0 V for versatile testing.
• Precise current generation: 0–24 mA with support for 0–20 mA and 4–20 mA standards, stable even with loads up to 500 Ω.
• Coarse and fine adjustment: Rotary encoder with 30 pulses per turn for smooth and precise control.
• Clear LED display: 4-digit display with 8 brightness levels and multiple presentation modes (actual value, percentage, special modes).
• Settings memory: Saves voltage/current values and offers quick start points for repetitive tasks.
• Three power options: External 15–30 V DC, micro USB 5 V, or built-in 1100 mAh lithium battery for field use.

Ideal for PLCs, inverters, proportional valves, transducers, and control systems. The FNIRSI SG-002 replaces several devices and gives you full control over analog signals in all conditions.
