Note Order 1x TB704 terminal block separately
Slot In the X20 CPU and expandable bus controller X20BC1083
Material number:
  • ASi interface master
  • Electrically isolated
  • 4-pin bus connector

The interface module is equipped with an ASi master interface. This allows third-party components to be integrated in the B&R system and makes it possible to quickly and easily transfer data in both directions. 

The interface module can be operated in X20 CPUs or in the expandable POWERLINK bus controller X20BC1083.
