Omron Temperature Controller E5CN-QMT-500

Core Specifications Category Details Product Type E5CN Series dual-output digital temperature controller (1/16 DIN) Manufacturer Omron Automation Mounting Panel mount (1/16 DIN: 48×48 mm cutout); screw terminals (-500 suffix) Power Supply 100–240 VAC (50/60 Hz, power consumption: ~6 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 3-digit LED (PV: red, 13.5 mm character height); 3-digit SV setting Control Method PID (auto-tuning AT), ON/OFF control, 2-PID (heating-cooling) control Control Output 2×voltage outputs (SSR drive: 12 VDC, 30 mA max each) Alarm Outputs 1×transistor output (PNP, 12 VDC, 21 mA max, short-circuit protected) Sampling Period 60 ms Indication Accuracy Thermocouple: ±0.3% PV; Pt/RTD: ±0.2% PV Front Protection NEMA 4X (IP66 equivalent) Operating Temperature -10°C to +55°C Certifications CE, UL, CSA, RoHS compliant Weight ~0.18 kg Key Functions & Advantages Dual SSR Voltage Outputs for Heating-Cooling Two independent 12 VDC/30 mA SSR drive outputs enable precise heating-cooling control (e.g., heater + chiller) with silent, high-frequency switching for stable temperature regulation. Auto-tuning PID minimizes overshoot/undershoot; 60 ms sampling ensures responsive load adjustment for dynamic processes. Universal Input & Basic Alarm Monitoring Works with all common thermocouples, RTDs, and analog inputs for seamless integration with existing sensors. 1 transistor alarm output (PNP, short-circuit protected) for high/low temp, sensor break, or heater burnout alerts. Compact Design & Durability 48×48 mm footprint fits tight panel spaces; screw terminals ensure secure wiring and easy maintenance. NEMA 4X (IP66) front panel resists moisture, dust, and chemical exposure in harsh factory settings.
