EMKO ESM-4450.1.20.2.1/00.00/0.0.0.0 PID process controller with universal input, 1 relay output, 2 slots for I/O expansion cards and a 230 V AC, RS485 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 a programmable universal input for thermocouples, resistance temperature detectors or analogue signals of 0–10 V or 0/4–20 mA.

The ESM-4450 PID controller can be used in a wide range of applications thanks to its universal process control input, multifunctional control outputs, selectable alarm functions, serial interface and input/output modules. The PID controller is primarily 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 features a PID self-optimisation function, which can be set to Auto Tune (cycle limit) or Self Tune (step feedback). The control outputs can be programmed for heating, cooling and alarm functions.
