EMKO ESM Series User Manual

PID Temperature Controller ESM-XX20
ENGLISH
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. Accurate and advanced controlling is
performed with selectable ON-OFF, P, PI, PD, PID and Self Tune PID
functions.
