CLS216
Multi-Loop PID Control
The CLS216 supports simultaneous PID control of up to 16 heating and cooling loops, making it ideal for large-scale systems requiring distributed temperature management. Each loop can be independently configured with auto-tune functionality, reducing setup time and ensuring optimal performance even for complex processes like plastic extrusion or batch chemical reactions .
Flexible Sensor IntegrationWith support for thermocouples, RTDs, and analog inputs, the controller accommodates diverse sensor types, minimizing inventory costs and simplifying retrofitting. Its sensor failure detection feature identifies open/short circuits or reversed connections, reducing downtime for troubleshooting .

CLS216
Advanced Communication Capabilities
Equipped with RS232 and RS485 ports, the CLS216 integrates seamlessly with SCADA systems, PLCs, and HMIs via Modbus RTU. This enables remote monitoring, data logging, and firmware updates, enhancing operational efficiency in distributed automation networks .
