Full-multi input adapts to diverse sensors (e.g., K-type thermocouple for high temp + Pt100 for ambient) without hardware changes, reducing inventory complexity. 50 ms sampling period ensures fast response in high-dynamic processes (e.g., 10+°C/min ramp rates in semiconductor curing). Advanced Safety & Monitoring 3 auxiliary relays enable multi-alarm logic (high temp + sensor fault + heater burnout) for layered protection, minimizing downtime in pharmaceutical manufacturing. Heater burnout detection (single/3-phase) alerts to element failures, preventing product defects in packaging machines. Output cycle counting tracks SSR/relay usage for preventive replacement, extending system lifespan. User-Friendly Operation & Maintenance Large PV display enhances visibility in dim control rooms; front-panel pushbuttons simplify auto-tuning and parameter adjustments. Event input supports external SP switching via PLC dry contacts, streamlining batch recipe changes in food processing lines. Non-volatile memory preserves parameters during power loss; tamper-proof settings prevent unauthorized changes in regulated industries.
