Omron Temperature Controller E5CN-Q2HBTD

Core Specifications Category Details Product Type E5CN series 1/16 DIN temperature controller (SSR voltage output, 2 aux relays, heater burnout detection, 24 V AC/DC) Manufacturer Omron Automation Mounting Panel mount (45×45 mm cutout); screw terminal block (tool-assisted wiring) Power Supply 24 V AC/DC (50/60 Hz); power consumption: ~3 VA Input Type Universal multi-input (thermocouple: B/E/J/K/L/N/R/S/T; RTD: Pt100/JPt100; software-selectable) Display 4-digit dual LED (PV: white 15.2 mm; SV: green 8 mm); status indicators (output ON/OFF, alarm, heater burnout, auto-tuning) Control Method PID with auto-tuning/ON/OFF; heating/cooling mode selectable Control Output 1×SSR voltage pulse (DC 12 V, 20 mA max; short-circuit protected, for external SSR driving) Auxiliary Output 2×independent SPDT relay alarms (250 VAC 2 A resistive max each; configurable for high/low temp, sensor fault, deviation, heater burnout) Key Monitoring Function Built-in heater burnout detection (monitors SSR load current to identify open-circuit heaters or SSR failures) Sampling Period 50 ms Indication Accuracy Thermocouple: ±0.3% PV ±1 digit; RTD: ±0.2% PV ±1 digit Front Protection IP50 Operating Temperature -10°C to +55°C (no condensation/icing) Certifications CE, UL, CSA, RoHS compliant Dimensions 48×48×95 mm (W×H×D) Weight ~150 g Key Functions & Advantages SSR-Optimized Precision Control DC 12 V voltage pulse output drives external SSRs for silent, contactless switching with minimal electrical noise—ideal for high-frequency cycling loads and noise-sensitive applications (e.g., semiconductor thermal processing). 50 ms fast sampling and PID auto-tuning minimize overshoot/undershoot, ensuring stable setpoint tracking in dynamic thermal processes. Universal input supports mixed sensor types (thermocouple/RTD) without hardware changes, reducing inventory and setup time. Comprehensive Safety & Heater Monitoring Built-in heater burnout detection identifies open-circuit heating elements or SSR failures in real time, triggering auxiliary alarms to prevent equipment damage and process downtime. 2 independent auxiliary relays enable multi-layered protection (e.g., high-temp shutdown, sensor break alert, heater fault warning) with configurable latching/non-latching logic. IP50 front protection resists dust ingress; short-circuit protection on SSR output enhances system reliability. Low-Voltage Compatibility & Integration Flexibility 24 V AC/DC power supply suits distributed control systems (DCS) and PLC-centric low-voltage architectures, eliminating the need for step-down transformers. Intuitive 3-button front panel enables fast setpoint adjustment and status checking; non-volatile memory preserves parameters during power loss. Compatible with Omron CX-Thermo software for batch parameter configuration and data logging, streamlining large-scale system deployment.
