## Long description

FNIRSI SG-003A is a compact adjustable current and voltage simulator designed for industrial signal testing and conversion. It measures and generates signals across a wide frequency range (0–9999 Hz) and includes a 3000 mAh battery for extended field use. The device displays values in physical and engineering units, shows real-time input/output curves on its LCD, and provides multiple ports and preset options for flexible signal simulation.
Advantages
The unit offers real-time curve display with adjustable sampling time, four preset value groups for quick output switching, and programmable outputs including monotone up, monotone down, and cyclic modes. It supports signal conversion between current and voltage and between various physical units, has PWM output with separately adjustable frequency and duty cycle, and features custom upper and lower output limits. Portable and easy to use, the SG-003A includes intuitive buttons with colored LEDs, overvoltage protection on input ports, and a standby time of up to 26 hours.
Suitable for
Troubleshooting and testing PLC systems
Process instrumentation calibration and verification
Testing electric valves and actuators
Signal simulation during development and maintenance of industrial control systems
Key specifications
Model: FNIRSI SG-003A
Frequency measurement range: 0–9999 Hz
Battery capacity: 3000 mAh (portable, up to 26 h standby)
Outputs: Current and voltage simulation, PWM with adjustable frequency and duty cycle
Presets: 4 groups of preset values
Display: LCD with real-time input/output curve and engineering units
Ports: Multiple ports — blue (IN-), red (OUT), black (COM), yellow (IN+)
Safety: Overvoltage protection on input ports
How to use
Connect the appropriate cables to the designated ports (IN+, IN-, COM, OUT) following the color coding. Power on the device and use the intuitive button interface to select measurement or output mode, view real-time curves, and choose or program preset values. Adjust output limits, PWM frequency, and duty cycle as required. For signal conversion, set the input unit and desired output unit using the device menu, then start the output sequence (monotone up/down or cyclic) and monitor values on the LCD.
Usage recommendations
Use the overvoltage-protected input ports to avoid damage from incorrect connections; verify wiring and units before applying signals to sensitive equipment. For prolonged field use, ensure the 3000 mAh battery is charged and carry spare cables. When calibrating instruments, allow the device to stabilize after mode changes before taking readings.
