4-, 8-, 16-Loop CLS200

The Watlow CLS200 is a powerful lineof controllers, combining performance and flexibility with compact design. The four, eight and 16-loop versions provide complete control solutions for thermoforming and other plastics processes. Support for multiple types of sensor inputs is available, including thermocouples, RTDs, linear voltage, current and frequency. Each controller can operate as a stand- alone system, and includes built-in serial communications for computer interface and data acquisition. An enhanced features option offers cascade control, ratio control, differential control, process variable retransmit and remote analog set point.The CLS200 controllers are UL Multiple and mixed inputs •Enhanced Features— includesthe standard firmware features with the addition of process variable retransmit, remote analog set point, cascade control, ratio control and differential control algorithms. Each channel can be configured for standard PID control or one of the other control algorithms. Each channel of cascade control or remote analog set point requires two controller channels. Unused control outputs on any channel can be configured for retransmit.Because the CLS200 has no onboardanalog outputs, applications that use process variable retransmit typically require one SDAC module per retransmitted signal. •Simply change sensor types atthe last minute•Less to learn, less inventory Sensor failure detection •Reduces time troubleshootingreversed, shorted and open sensors
