CelciuX° (EJ1)Advanced and Multi-Loop controllers
CelciuX° (EJ1) - Multi-Loop temperature control – Control and Connectivity
CelciuX° (EJ1) is designed to handle complex temperatureprofiles thanks to Omron’s unique Gradient temperatureControl (GTC) algorithm and to offer easy program-less communication with Omron and third-party PLCs andHMI. Aboveall,CelciuX° (EJ1)
incorporates all “simple to use” clever temperature control technology, like 2-PID, dis- turbance control and various ways of tuning.
• Interfaces to a wide range of industrial networks
• Reduced engineering due to Program-less communications, Smart Active Parts and
FunctionBlock Libraries
• Available with screw terminals and screw-less clamp terminals
• One unit handling various types of input, such as Pt, Thermocouple, mA, and V
• Gradient Temperature Control (GTC)

*1For heating/cooling control applications, the auxiliary outputs on the 2-point models are used for cooling control.
On the 4-point models, heating/cooling control can be performed for two input points only.
*2When using the heater burnout alarm, purchase a Current Transformer (E54-CT1 or E54-CT3) separately.
*3This unit mounts to the left of the CelciuX° (EJ1) configuration and enables PROFINET or Modbus/TCP network connection. Combine the HFU-ETN with an EDU_-NFLK end unit to use with other devices supporting Modbus-RTU like E5_N temperature controllers and MX2 Inverters.
*4An End unit is always required for connection to a Basic unit or an HFU. An HFU cannot operate without a Basic unit.
