EVO 150 | BST Accuweb

A compact 24V DC Web Guide Controller for brushed and brushless actuators.

The EVO 150 offers both versatililty and reliability in a remarkably small package. It integrates easily with industry standard networks and is compatible with all AccuWeb dynamically compensated WideArray™ and PointSource™ edge detectors that automatically calibrates the web guide system for environmental changes and process contamination.

The EVO 150 control module can be ordered for DIN rail mounting or in one of three IP65 rated enclosures

  • enclosure only
  • enclosure with switchpad
  • enclosure with touch screen HMI

24V DC Operation — Integrates easily into existing lines or control panels. 

150 Watts of Power — Enough power to control all web guiding actuators. 

Advanced Brushed or Brushless Drive – works with existing actuators and maintenance-free brushless motors. 

Network Friendly — EtherNet/IP, PROFINET I/O, and discrete I/O communication protocols allow easy interface with PLC networks. 

Web Accessible — Integrated web connection via standard EtherNet cabling allows convenient uploading and downloading of guide settings and performance data. 

Applications — Designed for web applications up to 40" wide. 

DualEdge™ Guiding — Capable of centerline guiding webs up to 18" wide using a single WideArray™ edge detector. 

Four Configurations — The EVO 150 control module is available for DIN rail mounting or in steel enclosure with optional switchpad or touch screen HMI.

Ratings — Enclosures are rated IP65 for protection from harsh environments, and designed to UL, EUL, CUL and CE codes. Reference UL certificates at www.ul.com.
