Virtually every machine uses e-stops to bring them to a safe, no-power state. With AS-Interface, the most common e-stop is designed so that all the necessary electronics are part of the e-stop.

But there is another approach: combining a more conventional dumb e-stop with a very small AS-Interface G10 safety module. Safety door switches are also very common. To allow the highest degree of flexibility, the keys that go along with these safety devices come in many designs depending on the kind and size of door.

Safe, contact-expansion relay modules for AS-Interface are used to expand the number of available safety outputs in cases where modern electronic safe outputs cannot be used.  Because they have no mechanical components that are more prone to fail, this approach has numerous advantageous for AS-Interface networks:

  • --Not using relays reduces the cost of the solution
  • --The switch-off time of an electronic output is faster
  • --Eliminating mechanical components increases total system reliability
  • --External relays reduce the cost of replacing a failed component
  • --Replacing just the contact expansion module is faster

This episode discusses more “slightly unusual” application-solver devices that make AS-Interface great.

The AS-Interface Movimot module is a great solution when AS-Interface is used to control the SEW MOVIMOT Gearmotor with integrated frequency inverter.

The Pepperl+Fuchs PTC protected passive splitter is used to protect the cable in case there is a short on the pigtail.

The AS-Interface 'Circuit Board' module is a great solution when profile height matters.  Using an AS-Interface circuit board module and pre-mounting it in a small housing with six 22 mm holes is another good solution for user input/feedback.

  • --The circuit board module is fully encapsulated and quickly mounted using hook & loop
  • --The modules are designed for pushbutton inputs, selector switches and LEDs that can be completely powered from AS-Interface
  • --The "flying lead" version further simplifies installation
  • --The LT3 module can be expanded to 8-in and 8-out by adding a second circuit board module

Most AS-Interface installations use 4-input or 4-input/4-output modules.  But there are many other AS-Interface devices, used less frequently, that are still very useful to know about. This episode covers some of those “application solvers.”

  • --Incandescent stack light elements are suitable when cost is top priority
  • --Light elements come in all standard colors
  • --The 'BUZZER' device is used to provide user information and allows feedback
  • --The 'BUZZER' offers illumination, a horn, and a capacitive touch button for user acknowledgment

AS-Interface is frequently used by mounting modules inside of cabinets and junction boxes. Many suppliers offer IP20 devices, but Pepperl+Fuchs' KE and KE1 AS-Interface modules are unique and offer a number of significant advantages:

  • --Color-coded removable terminals speed up installation and maintenance
  • --Versions with electronic and relay outputs add application flexibility
  • --DIP switch selectable AS-Interface/AUX sensor power
  • --Shallow KE1 design is ideal for compact junction boxes
  • --Port-specific output overload indication for fast troubleshooting

In this flashback episode, Tim and Helge discuss how AS-interface power supplies are different in several aspects.  AS-Interface power supplies provide a higher primary voltage and contain the decoupling circuit-enabling data and communication on the same cable.  Tim and Helge cover how to determine the size of the AS-Interface power supply.

  • -- AS-Interface power supply
  • -- Voltage
  • -- Current
  • -- How to size the power supply
  • -- Grounding and ground fault detection
