FNIRSI SG-002 is a compact, professional generator for service and commissioning that can generate voltage signals up to ±12 V as well as current loops 0–24 mA (including 4–20 mA). It supports active and passive modes, 2/3/4-wire connections, and thanks to a clear display and rotary encoder it enables fast yet very precise setup when testing PLCs, transmitters, valves, and analog inputs.
Clear control and quick value setting
The large rotary encoder enables coarse and fine adjustment of voltage/current, while LED indication and a mode button make switching functions easy. This lets you set the required value quickly, accurately, and without unnecessary steps.
Safe connection using removable terminals
Removable screw terminal blocks and clearly labeled contacts make wiring easy in active and passive mode and in 2/3/4-wire installations. They minimize the risk of measurement errors and speed up service work in control cabinets, on PLCs, and on transmitters.
Compact body for mobile service and field work
The rugged compact design with mounting holes fits even into tight spaces. With dimensions of 89 × 69 × 28 mm, the FNIRSI SG-002 is ideal for mobile diagnostics and commissioning of automation systems.
The FNIRSI SG-002 multifunction signal generator is designed for real industrial use—from quick diagnostics in a control cabinet to laboratory calibration. One device covers the most common analog standards, so you can easily simulate a sensor output, verify an analog input, or set up a control loop without additional power supplies or auxiliary resistors.
A wide range of voltage modes (including 0–10 V, 1–5 V, ±5 V, and others) together with a precise 0–24 mA current output makes the SG-002 a universal tool for automation, service, and training. Coarse and fine tuning via the rotary encoder speeds up work, and after calibration you can achieve high accuracy.
