Description
Product Description
The Watlow Anafaze CLS208 is an eight-loop industrial temperature and process controller in the CLS200 series. It provides independent control-loop functions for multi-zone heating and process applications, including industrial ovens, plastics processing equipment, thermal treatment systems, and production machinery.
The CLS208 supports multiple sensor types, including thermocouples, RTDs, and configured linear voltage or current inputs. Its control functions include PID regulation, alarm monitoring, and serial communication for configuration and supervisory data exchange. Optional features depend on the specific order code and installed configuration. Before replacement, verify the complete model suffix, input types, output hardware, power supply, and communication settings.
