Product description: Signal generator 0 - 24 V / 0 - 24 mA - FNIRSI SG-004A
The FNIRSI SG-004A is a compact, multifunctional signal generator designed for automation engineers and maintenance technicians. The device generates and measures signals in industry standards – from 0 mA to 24 mA, 0 V to 24 V, 0 Hz to 9999 Hz – as well as mV, resistance, and thermocouple signals . The SG-004A model features a real-time curve function, which allows viewing input and output signal changes in real time and recording measurement history. Modbus protocol support, programmable mode , and the ability to update firmware via USB significantly enhance the device's functionality. Thanks to its compact size and robust ABS housing with silicone protection, the generator is suitable for both workshop and field use.
Signal generator 0 - 24 V / 0 - 24 mA - FNIRSI SG-004A.
The SG-004A fits easily in your pocket or bag.
