Core Specifications Category Details Product Type E5EN Series advanced digital temperature controller (1/8 DIN) Manufacturer Omron Automation Mounting Panel mount (1/8 DIN: 96×48 mm cutout); screw terminals (-500 suffix) Power Supply 100–240 VAC (50/60 Hz, power consumption: ~8.5 VA) Input Type Universal input (thermocouple: K/J/T/E/R/S/B/N/L/U/W/PLII; RTD: Pt100/JPt100; analog: 4–20 mA/0–10 V/0–5 V/1–5 V/0–50 mV) Display Multi-segment LCD with three-color backlight (PV: white; SV: green; status: red); 5-digit PV (0.01°C resolution), 4-digit SV Control Method PID (auto-tuning AT), ON/OFF control, heating-cooling control Control Output 1×SPDT relay (5 A @ 250 VAC resistive) Alarm Outputs 2×SPDT relays (5 A @ 250 VAC resistive each) for high/low temp, sensor break, heater burnout Event Inputs 2 points (for run/stop, reset, remote SP, etc.) Sampling Period 250 ms Terminal Type Screw terminals (removable terminal block) Operating Temperature -10°C to +55°C Certifications CE, UL, CSA, RoHS compliant Weight ~0.26 kg Key Functions & Advantages Advanced Control & Diagnostics Auto-tuning PID optimizes control parameters automatically, minimizing overshoot/undershoot; supports heating-cooling control for applications requiring precise temperature cycling. Heater burnout detection, loop burnout alarm, and control output ON/OFF counter enable preventive maintenance to reduce downtime. Universal Input & Safety Interlocks Works with all common thermocouples, RTDs, and analog inputs for seamless integration with existing sensors. 2 auxiliary alarm outputs with logic operations (AND/OR) for customizable safety interlocks (e.g., high-temp shutdown, sensor failure alerts). High-Visibility Display & Flexibility Multi-segment LCD with three-color backlight ensures clear visibility of PV, SV, and status (auto/manual, RUN/STOP, alarms) in factory environments. Event inputs allow remote control and integration with PLCs or other automation systems; PF key enables one-touch access to frequently used functions (auto/manual, run/stop).
