Touchscreen operator interface – icon-based, language-independent for worldwide use - Processes two sensors – single controller handles dual sensor inputs - Multiple configurations – sensing/monitoring (D), web guiding (MD), with Ethernet options (Cx) - Industrial Ethernet options – EtherNet/IP, PROFINET, EtherCAT (on C models) - Analog outputs – ±10V, 0-10V, 0-20mA, 4-20mA programmable - Plug-and-play operation – simple menus for quick setup without specialized training ## Benefits - Stop losing hours to complex sensor setup and programming - Eliminate training costs – icon-based interface needs no language translation - End integration headaches – native industrial Ethernet protocols connect directly to your PLC - Remove troubleshooting delays – web browser dashboard for remote diagnostics (C models) - Prevent maintenance surprises – real-time sensor health monitoring - Stop paying for multiple controllers – one controller processes two sensors ## Applications - Edge position sensing and monitoring - Web guiding control for converting lines - Width measurement applications - Integration with plant PLC/SCADA systems - Multi-sensor processing for complex lines ## Product Details - **Web Widths:** Wide (48"-72"), Medium (12"-48") - **Line Speeds:** 100-500 fpm - **Material Types:** Mesh/Screen, Nonwoven - **Lead Time:** 2-3 Weeks ## Configurations (SKUs) - `4-100221`: SCU5 D+ -
