Watlow Anafaze CLS200 Series Controller

Product basic positioning and core advantages

1. Product positioning

The CLS200 series is a compact loop control system designed in a 1/8 DIN package, offering three versions: 4-loop (CLS204), 8-loop (CLS208), and 16 loop (CLS216), which can cover multi scenario temperature control requirements (such as industrial heating/cooling control, batch processing, etc.). The device supports independent operation and can also be connected to a computer system through serial communication for data acquisition and remote control, in compliance with UL standards ®、 C-UL ®  Certification and EU EMC directive, with CE mark.

2. Core advantages

Advantage categories, specific characteristics, and value

Space and efficiency: Single circuit occupies less panel space, supports multi circuit integration to reduce installation time, and reduces panel layout complexity

Easy to use Auto tune function; 32 character vacuum fluorescent display screen+8-key keyboard, menu guided operation reduces debugging threshold, precise control can be achieved without professional skills; Quickly complete parameter settings

Flexibility supports thermocouples RTD、 Multiple sensor inputs such as linear voltage/current, frequency, etc; 8 homework programs are stored and called to reduce spare parts inventory and learning costs, allowing for quick switching between different process flows

Reliability sensor fault detection (open circuit, short circuit, reverse connection); 34 digital outputs (50 pin terminal board configuration) shorten troubleshooting time and flexibly adapt to control and alarm requirements

Scalability supports EIA/TIA-232/485 serial communication; Optional DAC/SDA analog output module for easy integration with PLC and upper computer, meeting the requirements of analog signal conversion (such as process variable retransmission, motor speed regulation)

Core functions and firmware options

1. Basic control functions

PID control: Supports closed-loop PID control for up to 16 heating/cooling circuits, with 1-2 control outputs per circuit (supporting on/off time ratio and distributed zero crossing triggering).

Alarm function: Each input channel is equipped with independent process alarms (high/low limit) and deviation alarms, supporting user-defined dead zone, delay time, and startup suppression. The global alarm output can be linked to the PLC, and the watchdog output indicates the controller's operating status.

Data storage: capable of storing 8 job programs, supporting quick calling and switching of processes; The controller configuration can be imported/exported through the serial port.

2. Firmware version selection

Select firmware with different functions according to application requirements, and the core differences are as follows:

Firmware type, core functions, applicable scenarios

Standard firmware includes basic closed-loop PID, automatic tuning, alarm, job storage, sensor fault detection, and conventional temperature control scenarios such as constant temperature heating and simple cooling control

Ramp and Soak firmware includes standard functions+ramp heating/insulation control, process variable retransmission for complex batch processing (such as material aging testing, food processing, requiring staged temperature control)

Enhanced firmware includes standard functions+process variable retransmission, remote simulation set points, cascade control, proportional control, differential control, high-precision linkage control scenarios (such as multi loop coupling temperature control, remote set point adjustment)

Note: The serial control and remote simulation set point functions of the enhanced firmware require 2 controller channels to be occupied; Unused control outputs can be configured for process variable retransmission (with SDAC module).
