Front Protection IP66 Operating Temperature -10°C to +55°C Certifications CE, RoHS compliant Dimensions 48×96×78 mm (W×H×D) Weight ~200 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 2-channel heater burnout/SSR fault detection monitors 3-phase 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 24 VAC/DC power and full multi-input simplify global integration and sensor replacement without hardware changes.
