Omron Temperature Controller EJ1C-EDUA-NFLK

Core Specifications Category Details Product Type EJ1 series end unit (modular temperature controller system termination) Manufacturer Omron Automation Mounting DIN rail (15.7 mm width); M3 screw terminals (fixed) Power Supply 24 V DC (1.2 W max power consumption) Communication 1×RS-485 port (115 kbps max; CompoWay/F, Modbus RTU); 1×programming port Outputs 2×sinking transistor auxiliary outputs (max 30 V DC, 0.5 A per output) System Capacity Connects up to 16 EJ1 basic/high-function temperature control units Protection End unit case IP20; terminal section IP00 Operating Temperature -10°C to +55°C (no condensation/icing) Storage Temperature -25°C to +65°C Certifications UL 61010C-1, CSA C22.2 No. 61010.1 compliant Dimensions 90×31×70 mm (W×H×D); weight: ~70 g Key Functions & Advantages Modular System Termination Acts as the end plate for EJ1 temperature controller chains, enabling DIN rail assembly of up to 16 control units (basic/high-function) for multi-loop temperature systems (e.g., semiconductor thermal processing, packaging machines). Fixed M3 screw terminals ensure secure wiring for power, communication, and auxiliary outputs in industrial environments with vibration. Seamless Communication Integration RS-485 port supports Modbus RTU and CompoWay/F protocols, allowing connection to PLCs, SCADA systems, or HMIs for centralized data logging and remote control. Programming port facilitates local configuration via Omron software (e.g., CX-Temperature Control) without disrupting system operation. Auxiliary Output Flexibility 2 sinking transistor outputs (30 V DC, 0.5 A each) can trigger alarms, external relays, or process interlocks (e.g., heater shutdown on temperature deviation). Enables event-driven actions without additional I/O modules, reducing system cost and complexity.
