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 “simple to use” 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.
Multi-loop machine control with hmi
Control, overview and data-logging couldn't be easier with the CelciuX° in combination with a direct connection to Omron HMIs.
EJ1N-HFU-ETN
The EJ1N-HFU-ETN provides the solution to connect a CelciuX° (EJ1) in-panel multi-loop PID controller to PROFINET and Modbus/TCP. Although built on the CelciuX° (EJ1) platform, this unit can be used as a gateway for discrete Modbus units when only using the EJ1N-EDU endplate.
PRT1-SCU11
This gateway supports all CompoWay/F equipped products, including temperature controllers, digital panel indicators, etc. It can also be used for connecting MCW151-E and E5_K series.
CX-Thermo
Omron’s CX-Thermo support software has been specially developed for use with the company’s E5AC/E5CC/E5DC/E5EC, E5AN/E5GN, E5_N-H, E5ZN, E5AR, E5ER and CelciuXº temperature controllers. CX-Thermo enables faster parameter set-up, easier device adjustment and simpler maintenance. It dramatically reduces the time and effort needed to set and manage temperature control parameters.
CX-One
CX-One software allows users to build, configure and program a host of devices such as PLCs, HMIs and motion-control systems and networks using just one software package with one installation and license number. This greatly reduces the complexity of the configuration and allows automation systems to be programmed or configured with minimal training.
CX-Supervisor
CX-Supervisor boasts powerful functions for a wide range of PC based HMI requirements. Simple applications can be created rapidly with the aid of a large number of predefined functions and libraries, and even very complex applications can be generated with a powerful programming language or VBScript™. CX-Supervisor has an extremely simple, intuitive handling and high user friendliness. Importing ActiveX® components makes it possible to create flexible applications and extend functionality.
