CelciuX° (EJ1) Advanced and Multi-Loop controllers CelciuX° (EJ1) - Multi-Loop temperature control – Control and Connectivity CelciuX° (EJ1) is designed to handle complex temperature profiles thanks to Omron’s unique Gradient temperature Control (GTC) algorithm and to offer easy program-less communication with Omron and third-party PLCs and HMI. Above all, 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 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 • Gradient Temperature Control (GTC) Ordering information Type Control points Control outputs Auxiliary outputs Other functions Terminal Order code Basic unit 2 2 voltage (pulse) 2 transistor (NPN) *1 2 CT input *2 + 2 event input M3 screws EJ1N-TC2A-QNHB Basic unit 2 2 voltage (pulse) 2 transistor (NPN) *1 2 CT input *2 + 2 event input Screw-less clamp EJ1N-TC2B-QNHB Basic unit 2 2 current 2 transistor (NPN) *1 2 event input M3 screws EJ1N-TC2A-CNB Basic unit 2 2 current 2 transistor (NPN) *1 2 event input Screw-less clamp EJ1N-TC2B-CNB Basic unit 4 4 voltage (pulse) – – M3 screws EJ1N-TC4A-QQ Basic unit 4 4 voltage (pulse) – – Screw-less clamp EJ1N-TC4B-QQ High function unit – – 4 transistor (NPN) 4 event input M3 screws EJ1N-HFUA-NFLK High function unit – – 4 transistor (NPN) 4 event input Screw-less clamp EJ1N-HFUB-NFLK DeviceNet unit – – – – Screw connector EJ1N-HFUB-DRT Ethernet unit*3 End unit *4 – – – – 3 x RJ45 EJ1N-HFU-ETN – – 2 transistor (NPN) – M3 screws EJ1C-EDUA-NFLK End unit *4 – – 2 transistor (NPN) – Removable Connector EJ1C-EDUC-NFLK *1 For 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. *2 When using the heater burnout alarm, purchase a Current Transformer (E54-CT1 or E54-CT3) separately. *3 This 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. *4 An End unit is always required for connection to a Basic unit or an HFU. An HFU cannot operate without a Basic unit.

A GTC (Gradient Temperature Control) basic TC unit always requires a GTC HFU unit. Accessories Current transformer Diameter Order code 5.8 dia. E54-CT1 12.0 dia.
