Omron Temperature Controller E5CC-QX3ASM-001

Core Specifications Category Details Product Type E5CC Series 48×48 mm temperature controller (SSR voltage, 3 aux relays, single-phase heater/SSR fault detection, RS-485, 100–240 VAC, screw terminals) Manufacturer Omron Automation Mounting Panel mount (45×45 mm cutout); screw terminal block Power Supply 100–240 VAC (50/60 Hz); power consumption: ~7.5 VA Input Type Full multi-input (thermocouple: K/J/T/E/R/S/B/PLⅡ; Pt100 RTD; 0–20/4–20 mA, 0–5/1–5/0–10 V analog; software-selectable) Display 4-digit dual LED (PV: white 15.2 mm; SV: green 8 mm); status indicators (auto-tuning, alarm, control action, communication, heater fault) Control Method ON/OFF, 2-DOF PID with auto-tuning (heating-only or heating/cooling selectable) Control Output 1×SSR voltage (DC 12 V, 20 mA max; for SSR driver circuits) Auxiliary Output 3×independent relay alarms (SPST-NO, 250 VAC 2 A resistive max each; configurable for high/low temp, sensor fault, process deviation, heater fault) Heater Monitoring Single-phase heater burnout/SSR fault detection (1-channel) Event Input 2 points (for run/stop, remote SP, auto-tuning trigger) Communication RS-485 (Modbus RTU; up to 32 units on bus; 1200–19200 bps) Sampling Period 50 ms Indication Accuracy Thermocouple: ±0.3% of PV; Pt100: ±0.2% of PV; analog: ±0.2% of F.S. Front Protection IP66 Operating Temperature -10°C to +55°C Certifications CE, RoHS compliant Dimensions 48×48×60 mm (W×H×D) Weight ~150 g Key Functions & Advantages Precision SSR Control & Fast Response SSR voltage output enables silent, contactless switching for stable heating control with minimal electrical noise; ideal for resistive loads or SSR-driven contactors. 50 ms sampling period ensures rapid detection of temperature fluctuations, critical for high-precision processes like heat treatment. 2-DOF PID with auto-tuning optimizes setpoint tracking and disturbance rejection, reducing overshoot/undershoot in dynamic loads. Comprehensive Safety & Reliability Single-phase heater burnout/SSR fault detection monitors heater current and SSR operation, preventing equipment damage and downtime. 3 independent alarms provide multi-layered protection (e.g., high-temp shutdown, sensor break, heater fault) without additional hardware. IP66 front protection resists dust/water ingress in harsh industrial environments; password lock prevents unauthorized parameter changes. Flexible Integration & Maintenance RS-485 Modbus RTU enables seamless connection to PLCs/HMIs for centralized monitoring and parameter adjustment. 2 event inputs support remote control (run/stop, SP adjustment) and auto-tuning triggers, enhancing system automation. Universal 100–240 VAC power and full multi-input simplify global integration and sensor replacement without hardware changes.
