WATLOW CLS216
Main Features and Advantages
Advanced Thermal Control: The CLS216’s predictive PID algorithm with a 100ms sampling rate prevents overshoot in injection molding barrel temperature control. Its dual-setpoint capability allows automatic switching between heating/cooling profiles during polymer extrusion processes。
Connectivity: Built-in OPC UA server enables direct data exchange with SCADA systems without additional gateways。The web interface supports remote recipe management for multi-batch chemical reactors。
Durability: Military-grade components ensure 100,000+ operation cycles in metal heat treatment furnaces。The front panel’s IP66 rating protects against high-pressure cleaning in dairy processing lines。
