The FNIRSI SG-004A generates and measures current, voltage, frequency, PWM, RPM and count signals. It also supports WRE25/26 and S, B, K, R, J, T and N-type thermocouples, as well as Pt100 and CU50 resistance temperature detectors.
The 2.4″ color TFT LCD displays real-time measurements and curves, with automatic scale adjustment. The device stores 30 sets of historical data, while RS485 communication allows it to connect to configuration software or a PLC.
