PID TEMPERATURE CONTROL UNITS
ESM-4420 , ESM-7720 , ESM-9920
PID Temperature Control Units
- 4 digit process (PV) and 4 digit set (SV) display
- Process input (TC, RTD)
- Programmable ON/OFF, P, PI, PD and PID
control forms
- Adaptation of PID Coefficients to the system with
Self-Tune operation (Step Response Tuning)
- Programmable Heating or Cooling Functions for
Control Output
- Selectable Alarm Functions for Alarm Output
ESM series temperature controllers are designed for measuring and
controlling a process value. They can be used in many applications
with their TC and RTD temperature measurement input, multi-function
control outputs, selectable alarm functions.
They are mainly used in glass, plastic, petro-chemistry, textile,
automotive and machine production industries.
advanced controlling is performed with selectable
PID and Self Tune PID functions.
