Product description: Signal generator 0 - 24 V / 0 - 24 mA - FNIRSI SG-003A
The FNIRSI SG-003A is a portable signal generator and simulator designed for industrial automation maintenance, PLC diagnostics, transducer testing, and measurement device calibration. It allows for the generation and measurement of current, voltage, and frequency signals , as well as their linear conversion between various physical values. The generator supports active and passive current signals from 0 mA to 24 mA, voltages from 0 V to 24 V, PWM signals, and frequencies up to 9999 Hz . Real-time waveform display allows you to monitor changes in input and output signals on the TFT screen . Its compact design, measuring 112 x 82 x 27 mm and weighing 165 g, makes the generator ideal for field use.
