Watlow CLS208 C10000CP high-performance, 8-loop PID temperature controller

The Watlow Anafaze CLS208 C10000CP is a high-performance, 8-loop PID temperature controller designed for precision and reliability in complex industrial processes.

As part of the venerable CLS200 series, this specific model is optimized for multi-zone thermal management where space efficiency and advanced control algorithms are paramount.

1. Introduction

The CLS208 C10000CP is a dedicated 8-channel controller that combines the power of a programmable logic controller (PLC) with the ease of use of a standalone PID unit.

It features an integrated vacuum fluorescent display (VFD) and a tactile keypad, providing a complete user interface for real-time monitoring and configuration.

The C10000CP configuration typically denotes a specific build including standard EPROM firmware and high-density connectivity via SCSI or terminal board options.

3. Product Advantages and Features

Adaptive Tuning: Includes Watlow’s proprietary algorithms to automatically calculate PID parameters, reducing setup time and process oscillation.

Job Memory: Allows users to store up to 8 unique “Jobs” (recipes), enabling rapid switching between different production runs.

High Density: Manages 8 loops in a compact 1/8 DIN package, significantly reducing panel space compared to eight separate controllers.

Sensor Health Monitoring: Built-in diagnostics detect reversed, shorted, or open sensors, preventing process errors and potential safety hazards.

4. Application Cases

Plastic Injection Molding: Precise control of multi-zone runner systems and barrel temperatures.

Semiconductor Processing: Critical temperature regulation for wafer bake-out and chemical handling.

Packaging Machinery: Managing multiple heat-seal bars and glue stations on high-speed lines.

Composite Curing: Orchestrating complex ramp and soak profiles in industrial ovens or autoclaves.

5. Other Models in the Same Series

CLS204: 4-loop entry-level version for smaller systems.

CLS216: 16-loop high-density version (single-ended inputs).

CLS200 Enhanced: Supports cascade control, ratio control, and differential control algorithms.

CAS200: A DIN-rail mount “blind” version for systems requiring a separate HMI.

6. Installation and Maintenance

Installation

Mounting: Install in a standard 1/8 DIN panel cutout. Ensure at least 1 inch of clearance for rear wiring and ventilation.

Wiring: Use shielded twisted-pair wiring for all sensor inputs. Keep low-voltage signal wires separate from high-voltage AC power lines to avoid EMI.

Expansion: For the full 34 digital outputs, connect via the 50-pin SCSI port to a TB50 terminal board.

Maintenance

Battery Check: The RAM is battery-backed; verify the battery status via the diagnostic menu every 2 years to prevent loss of configuration.

Calibration: Re-verify input accuracy annually using a NIST-traceable calibrator.

Cleaning: Use a damp, soft cloth for the VFD display. Avoid harsh chemicals that may degrade the keypad membrane.

7. Unique Product Description

“The Watlow CLS208 C10000CP is the ‘Swiss Army Knife’ of multi-loop control.

It bridges the gap between basic thermal regulation and high-level automation by packing eight channels of surgical PID precision into a single 1/8 DIN interface.

Whether you are managing an intricate extrusion line or a delicate semiconductor process,

the CLS208 offers the visibility of a dedicated display with the industrial backbone of Watlow’s Anafaze heritage.”
