SCR
System Configuration
●
This system controls one loop.
- A type K thermocouple is used for the temperature sensor input.
- The temperature range is 0.0 to 500.0
°
C.
- The output is 4 to 20 mA and heater control is performed using a Thyristor Unit (Power Controller).
- Continuous proportional PID is set.
Note:
The default operation cycle (1 s) is used.
●
The screen for the Loop Controller is displayed by connecting a NS-series PT (Touch Panel).
