cascade controller, very useful when the heat is not produced where it is used ( for exemple heating of a chemical reactor through a enveloppe)
PID parameters
for sensitive application, there is the possibility to limit the controller output or limit the difference between the internal and external measured values
it can also be used as a conventional PID controller
2 inputs for sensor (Pt100, thermocouple, 0/4-20 mA),
2 relays outputs (max. 230 V, 2 A) or 24 V output in option (internal resistance 1 kohms)
2 relays for alarms
2 analog outputs 0/4-20 mA or digital output (to send the measured value, setpoint, etc… to other devices)
analog or digital input (for external setpoint, external controller starting,…)
