EMKO ESM-4450 PID process controller with universal input, 1 relay output, 2 slots for I/O expansion cards and communication interface

EMKO ESM-4450 PID controller for temperature sensors and analogue signals with two slots for I/O expansion modules

4-digit PID Process controller with programmable universal input for thermocouples, resistance thermometers or analogue signal 0-10 V, 0/4-20 mA.

The PID controller ESM-4450 can be used for many applications with the universal process control input, multifunctional control outputs, selectable alarm functions, serial interface and input/output modules. The PID controller is mainly used in the glass, plastics, chemical, oil, textile, automotive and mechanical engineering industries. The control mode can be set to ON-OFF, P, PI, PD or PID. The PID controller also has a PID self-tuning function, adjustable to Auto Tune (cycle limit) or Self Tune (step feedback). The control outputs can be programmed for heating, cooling and alarm functions.
