WATLOW ANAFAZE CAS 16CLSCAS Thermal control loop host

WATLOW ANAFAZE CAS 16CLSCAS Thermal control loop host

I. Model and Brand Positioning
Brand: WATLOW (a professional thermal control manufacturer from the United States) – ANAFAZE Sub-product Line
Full model interpretation: 16CLSCAS
CAS = Compact Anafaze System – Compact multi-loop thermal control platform
16CLS = 16 Loop Control System – Mainframe for 16 independent PID temperature control loops
The suffix “CAS” represents the complete unit (including display operation panel + mainframe integrated)
Product Positioning: High-density multi-channel universal temperature controller, positioned between single-loop temperature control instruments and large-scale DCS, suitable for multi-zone synchronous temperature control scenarios in semiconductor, heat treatment, ovens, and precision hot forming

 Core Channels and Input Specifications
1. Signal Input (16 channels fully isolated universal input)
Thermocouple TC: J/K/T/E/N/R/S/B – Full range, built-in cold junction compensation
Thermoresistor RTD: Pt100, Pt1000, Ni120 (2/3-wire compatible)
Analog signals: mV, 4–20mA, 0–10VDC pressure / flow signals
Sampling accuracy: ±0.1% FS, 24-bit ADC, resolution 0.01℃
Single-channel independent short circuit, over-range, sensor short circuit diagnostic alarms
2. Control Output (each channel selectable)
Pulse DC output: drives SSR solid-state relays (mainstream heating control)
Relay contact output (switching on/off)
Continuous adjustable analog 4–20mA / 0–10V output (for proportional valves, water cooling regulating valves)

Control Algorithm Function
Standard adaptive PID (TRU-TUNE automatic self-tuning), supports single PID, dual PID, cascade, proportional limit
Slope heating / holding segmented process curve programming, multi-segment temperature program automatic operation
High and low temperature over-temperature, temperature difference, rate over-limit 24 independent alarms, supports external interlock shutdown
Mathematical operation module: temperature difference, average value, high-low selection, logical AND/OR, simplifies PLC matching program

Communication and Networking
Standard Modbus RTU (RS485), can be connected to PLC, upper-level SCADA, data recorder
Anafaze internal bus: multiple 16CLS can be connected in parallel for networking, unified configuration and monitoring
Optional extended Ethernet Modbus TCP for remote monitoring, data record upload

 Electrical and Environmental Parameters
Power supply: 24VAC 50/60Hz, maximum 15VA of the entire unit
Operating environment: 0℃ ~ +80℃, humidity 0~90% without condensation, DIN rail installation inside the cabinet
Safety certification: UL, CE, RoHS, SEMI F47 semiconductor standard, Class1 Div2 explosion-proof optional configuration (Wattlow)
Structural dimensions: Standard 1/8 DIN integrated panel installation, built-in LCD digital display + key operation panel

Typical Application Scenarios
Multi-zone synchronous temperature control for semiconductor diffusion furnaces, coating equipment
Multi-channel temperature closed-loop control for industrial heat treatment furnaces, ovens, vacuum chambers
Batch temperature control for pharmaceutical and food production lines
Independent adjustment of multiple mold temperatures for injection molding, hot pressing forming equipment
Replacement of multiple single-loop temperature control instruments in old production lines to save control cabinet space

Differentiation of Series Models Table
Model Number of Circuits Location
CLS204 / CAS4CLS 4 Circuits Compact 4-zone equipment
CLS208 / CAS8CLS 8 Circuits Medium-sized oven, small thermal equipment
16CLSCAS 16 Circuits Large multi-zone complete equipment (mainstream spare parts)

Key Points for Maintenance and Replacement
The entire machine is of integrated panel type, and the main unit / display cannot be separated; replacement must be of the same model 16CLSCAS
Supports online modification of PID parameters and process curves, without the need for shutdown
RS485 bus wiring is recommended to use double-layer shielded twisted pair; for long distances, terminal resistors need to be matched
The original factory has partially discontinued production, and the market circulation mainly consists of disassembled test spare parts; before installing, the sensor channels need to be calibrated
