Features

CelciuXº - Multi-Loop temperature control - Control and Connectivity

CelciuXº is designed to offer easy program-less communication with Omron and third-party PLCs and HMI. Above all, CelciuXº (EJ1) incorporates all âsimple to useâ clever temperature control technology, like 2-PID, disturbance control and various ways of tuning.

  • Interfaces to a wide range of industrial networks
  • Reduced engineering due to Programm-less communications, Smart Active Parts and Function Block Libraries
  • Available with screw terminals and screw-less clamp terminals
  • One unit handling various types of input, such as Pt, Thermocouple, mA, and V input

Applications

The perfect solution for multi-loop control

Reliability, compactness and uncompromising control performance make the CelciuX° the perfect choice for basic multi-loop control.
