Description
Watlow CLS216 (Anafaze CLS200 Series) 16-Loop Multi-PID Temperature Control Module
Product Description
The CLS216 is a high-density multi-loop PID temperature controller module manufactured by Watlow under the legacy Anafaze CAS200 / CLS200 product family. This board provides 16 independent control loops within a single compact unit, replacing numerous standalone single-loop controllers to save cabinet space and reduce wiring complexity. It accepts universal sensor inputs and executes closed-loop PID or on/off temperature regulation with built-in ramp-and-soak profile programming. Integrated serial communication enables host system connection for recipe management, remote setpoint adjustment and real-time data acquisition. Widely used for multi-zone thermal processing, this module is a legacy industrial control component with proven stability for continuous thermal-critical manufacturing processes.
