AS-Interface, the recognized cabling system for sensors and actuators, has been enhanced. Standard process information and information relating to safety can now be transmitted over the same yellow cable. Capable of managing safety functions up to category 4 of standard EN-954-1/ISO 13849-1 and conforming to SIL 3 of standard IEC 61508, the AS-Interface “Safety at work” system meets the needs of the most common safety monitoring applications, such as:

• Emergency stops with instantaneous break contacts (stop category 0)
• Emergency stops with delayed break contacts (stop category 1)
• Safety interlocks and limit switches with and without interlocking
• Light curtains, etc.

Features and Benefits

• • Safety
  - Category 4 according to EN954-1
  - SIL 3 according IEC 61508
• Simplicity
  - just add the required safety devices to the standard AS-Interface network
• Integration
  - standard data and safety relevant data transmitted over the same communication bus, i.e. no need for a separate safety network
• Flexibility
  - monitor multiple devices and control multiple safety sectors
• Diagnose
  - from one screen, see the status of the safety interfaces and the system
• Multifunctional
  - able to monitor up to 31 safety interfaces
  - available with 1 or 2 independent output groups
• Segmentation of Safety Sectors
  - multiple safety monitors can be connected to the monitors can be configured to monitor different groups of safety interfaces
• Reduction in installation time
  - Saves 40% on installation cost
