Omron Temperature Controller E5AN-R3HT

Core Specifications Category Details Product Type E5AN Series digital temperature controller (1/8 DIN) Manufacturer Omron Automation Mounting Panel mount (1/8 DIN: 48×96 mm cutout); screw terminals (removable terminal block) Power Supply 24 VAC/DC (50/60 Hz, power consumption: ~5 VA) Input Type Universal input (thermocouple: K/J/T/E/R/S/B/N/L/U/W/PLII; RTD: Pt100/JPt100) Display 3-digit LED (PV: red, SV: green); status indicators (output, alarm, auto-tuning) Control Method ON/OFF control, PID control (auto-tuning AT); control period: 2/20 s (selectable) Control Output 1×relay output (SPDT, 250 VAC 5 A resistive load, 30 VDC 5 A resistive load) Alarm Outputs 2×independent transistor outputs (PNP, 12 VDC, 21 mA max each, short-circuit protected) Sampling Period 500 ms Indication Accuracy Thermocouple: ±0.3% PV ±1 digit; RTD: ±0.2% PV ±1 digit Front Protection IP40 (panel-mounted) Operating Temperature -10°C to +55°C Certifications CE, UL, CSA, RoHS compliant Weight ~0.2 kg Key Functions & Advantages Relay Control Output for Robust Switching SPDT relay output handles high-power resistive loads (heaters, contactors) with reliable mechanical switching; ideal for applications where SSR compatibility is unnecessary or relay durability is preferred. Auto-tuning PID minimizes overshoot/undershoot, ensuring stable temperature regulation in dynamic heating processes. Dual Transistor Alarms & User-Friendly Setup 2 independent transistor outputs support high/low temperature, sensor break, or heater burnout alarms—enhances process safety and integrates with PLC/HMI for remote monitoring. Removable screw terminals simplify wiring and maintenance; push-button configuration allows quick adjustment of input type, control parameters, and alarm settings without complex programming. Compact Design & Global Compatibility 48×96 mm 1/8 DIN footprint fits standard panel cutouts; 24 VAC/DC power suits low-voltage industrial systems and battery-backed installations. IP40 front protection resists dust and splashes; robust construction withstands industrial vibration/shock.
