Omron Temperature Controller E5AJ-A2HB-F

Core Specifications Category Details Product Type E5AJ Series 1/4 DIN fuzzy self-tuning temperature controller (1-alarm, 2-PID) Manufacturer Omron Automation Mounting Panel mount (96×96 mm cutout); plug-in terminals Power Supply AC 100–240 V (50/60 Hz, power consumption: ~14 VA) Input Type Universal multi-input: TC (K/J/T/L/U/N/R/S/B/E), RTD (Pt100/JPt100) Control Method Fuzzy self-tuning advanced PID (2-PID) control, ON/OFF control selectable Control Output 1×SPDT relay (250 VAC 3 A resistive max) Alarm Output 1×SPST-NO alarm relay (250 VAC 1 A resistive max, supports heater burnout/sensor fault) Display Dual 4-digit LED (PV: 15 mm red; SV: 10.5 mm green) Sampling Period 200 ms Indication Accuracy ±0.5% full scale ±1 digit Front Protection IP40 (panel-mounted) Operating Temperature -10°C to +55°C Certifications CE, UL, CSA compliant Weight ~200 g Key Functions & Advantages Fuzzy Self-Tuning Advanced PID Control Fuzzy self-tuning 2-PID algorithm adapts to process changes, minimizing overshoot/undershoot and shortening stabilization time. Universal input supports quick sensor replacement without hardware modifications, suitable for diverse industrial applications. Selectable ON/OFF control for simple heating/cooling systems requiring basic on-off switching. Heater Burnout & Sensor Fault Monitoring 1 independent alarm relay enables high/low temperature, deviation, heater burnout, or sensor fault alarms for enhanced process safety. Configurable alarm logic (latching/non-latching) to prevent false triggers during transient conditions. Front keys for easy alarm setpoint adjustment and status monitoring. Reliable & User-Friendly Design Plug-in terminals allow fast replacement and reduced downtime during maintenance. Nonvolatile memory retains settings during power loss; key protection prevents unauthorized changes. Wide AC 100–240 V power range suits global industrial environments.
