The Micro 4000NET  is designed to handle the most demanding web guide applications.

The Micro 4000NET controller is the heart of the industry’s most advanced web guide system. It is designed to handle any application, perform in any environment, and guide all web materials.

The Micro 4000NET offers outstanding flexibility by interfacing with existing customer networks and PLCs. The result is the ability to provide unmatched accuracy, consistency and reliability. It is compatible with all of AccuWeb’s dynamically compensated WideArray™ and standard edge detectors, AccuBeam® 3 line guide, and all linear actuators — all in one enclosure.

Remote guide point adjust station

Digital Speed and Accuracy — Automatically calibrates the web guide system for environmental changes, web process contaminents, and web edge changes every 4 milliseconds.

Dynamically compensated edge detectors

Operator Friendly — Intuitive touch pad interface with LED indicators. Setup parameters are located inside the controller, safe from inadvertent adjustments.

Digital line guides

No Setup Downtime
The system performs continuous automatic calibration of edge detectors through AccuWeb’s exclusive dynamic compensation process.

High performance electromechanical actuators (150 – 1500 lbs of thrust)

Network Friendly – Optional fieldbus adapters easily interface with most popular fieldbus networks, including ControlNet™, DeviceNet™, Modbus Plus, Profibus®-DP, and Ethernet protocols. Discreet I/O interfacing is a standard feature.

Hazardous Duty — Optional provisions for use in Class I Division 1 hazardous environment. Note: control enclosure must be located outside of the hazardous environment.Reference UL certificates at www.ul.com.

Ratings — Enclosure is rated IP65 for protection from harsh environments, and designed to UL, EUL, CUL, CE and FCC codes.

Easy Installation – All components are contained within this single enclosure – reducing interconnections and easily installs on web guide equipment next to the web guide frame.  

You’ll always get more value from AccuWeb

• PWM (Pulsed Width Modulated) actuator motor drives for quick, accurate response.
• Compact self-contained design requires no additional boxes or drives.
• Capable of web oscillation and electronic guide point adjustment.
• Ideal for laminating applications, software controls the positioning of one web relative to a second web or multiple webs.

The Micro 4000NET can handle EVERY
web guide application
