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

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

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

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.
