Omron Temperature Controller E5CN-C2TC

Core Specifications Category Details Product Type E5CN Series 1/8 DIN basic-type digital temperature controller (current output, 2 alarms, universal input) Manufacturer Omron Automation Mounting Panel mount (48×96 mm cutout); screw terminal block Power Supply 100–240 VAC (50/60 Hz); power consumption: max 7.5 VA Input Type Universal (thermocouple K/J/T/E/R/S/B/N, Pt100 RTD) Display 4-digit LED (PV/SV); 0.1°C resolution Control Method PID control with auto-tuning; ON/OFF control selectable Control Output 1×4–20 mA current (max load resistance: 600 Ω) Auxiliary Output 2×SPDT alarm relays (250 VAC 2 A resistive max each) Event Input 1 point (remote SP, run/stop, reset, etc.) Sampling Period 50 ms Indication Accuracy Thermocouple: ±0.3% PV ±1 digit; RTD: ±0.2% PV ±1 digit Front Protection IP66/NEMA 4X (waterproof/dustproof) Operating Temperature -10°C to +55°C Certifications CE, RoHS compliant Weight ~200 g Dimensions 48×96×78 mm (depth) Key Functions & Advantages Current Output & Universal Input 4–20 mA current output enables precise analog control of valves, variable frequency drives (VFDs), or other analog-controlled actuators for continuous heating/cooling regulation. Universal input covers a wide temperature range (-200°C to +2300°C for thermocouples, -200°C to +850°C for RTDs) for flexible sensor integration. 2 independent alarm outputs support high/low temperature or process fault monitoring for early intervention. User-Friendly Operation & Durable Design Screw terminals ensure secure wiring; compact 1/8 DIN form factor fits standard control panels. Intuitive front-panel keys with password protection prevent unauthorized parameter changes; non-volatile memory retains settings through power cycles. IP66 front protection withstands harsh industrial environments (chemical splashes, dust, moisture); CE/RoHS compliance meets global standards. Reliable Control Performance 50 ms high-speed sampling ensures rapid response to temperature changes for dynamic processes. Auto-tuning PID optimizes control parameters automatically, reducing setup time and ensuring stable performance across varying loads.
