▲ 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.
