Features and Drawings of Temperature Control Block

MELSEC-F Series Temperature Sensor Analog Input Adapter / Temperature Control Block: related image

Drawing

  • Four channels of temperature sensor input, low-voltage signal input and control output are combined into a single unit, to achieve "2-position control, standard PID control (auto tuning is possible), heating/cooling PID control, and cascade control."
  • Cascade control using 2 master/slave control loops permits quick temperature control in response to temperature shift caused by external disturbance, etc.
  • Heating/cooling PID control can be performed using one unit, allowing for both heating output and cooling output, which enabling up to 4 loops of heating/cooling control by operating both heating output and cooling output.
  • 13 types of thermocouple sensors and 3 types of Pt sensors (Pt100, JPt100, Pt1000) can be connected.
