Input device for temperature sensor
Analog control
Input device for
temperature sensor
Platinum resistance thermometer sensor (Pt100) or thermocouple temperature sensors can be connected.
FX3U-4LC type temperature control module, which provides PID control function with auto tuning, can use a function of
intelligent function module to perform temperature control.
