Description
1. Product Overview
The Watlow CLS216 is a versatile and compact 16-loop controller part of the Series CLS200 family. It is an ideal solution for industrial thermal processes that require multiple control loops in a small footprint, such as plastic processing, semiconductor manufacturing, and packaging machinery.
The CLS216 offers sophisticated PID control for each of its 16 channels, ensuring precise temperature stability and process accuracy. Its DIN-rail mount design allows for easy integration into control cabinets, while its robust communication capabilities enable seamless data exchange with PLCs, HMIs, or PC-based SCADA systems. By consolidating 16 controllers into one module, the CLS216 significantly reduces wiring time, hardware costs, and maintenance complexity.
Key Applications:
- Plastic Extrusion & Injection Molding: Multi-zone barrel and die temperature control.
- Semiconductor Processing: Precise wafer heating and chemical delivery systems.
- Packaging Machinery: Managing multiple heat-sealing bars and glue application zones.
- Laboratory & Medical Equipment: Multi-chamber environmental control and incubation.

7. FAQ
Q: Can the CLS216 handle different input types on different loops simultaneously?
Typically, the CLS200 series is configured for a specific group of input types. However, its universal input design allows for significant flexibility. Check your specific model suffix (e.g., CLS216-XXXX) for the exact input configuration.
Q: Is there software available to configure all 16 loops at once?
Yes, Watlow provides configuration software (such as WATVIEW) that allows you to set up, monitor, and log data for all 16 loops from a single PC interface via the Modbus™ port.
Q: What happens if one loop fails?
The CLS216 is designed for high reliability. Because the loops are independent in software, a sensor failure on one loop will not affect the PID execution of the other 15 loops.
