Passive distributors and active distributors by Bihl+Wiedemann

It makes no difference whether active or passive: when it comes to powering sensors and actuators, the newest distributor generation from Bihl+Wiedemann is the perfect solution for any system concept. Nor does the user need to worry about line protection: this is already integrated into both the active and passive distributors. The next pages show the benefits of the new distributor generation from Bihl+Wiedemann.

Passive distributors and active distributors

Generally there are two common ways of connecting and powering sensors and actuators to AS-Interface. For components with AS-i already on board, a simple passive Distributor is all that is needed (Fig., left). But even for completely normal standard modules without AS-i there is an efficient solution: they can be easily incorporated into the network using so-called active distributors (Fig., right) with integrated AS-i Chip.

Profile cable installation with Bihl+Wiedemann

 

(Click to enlarge)

Conventional installation

  • For each conventional module (1 × AS-i profile cable, 1 × AUX profile cable) 2 passive distributors and therefore up to 4 AS-i end caps are needed
  • It is not possible to start/end the profile cable directly in the module

Installation with the new passive distributor

  • The passive distributors with protection rating IP67 are suitable as a start or end point of the profile cables
  • No additional end caps are required. The AS-i/AUX profile cable can begin or end directly in the module ( IP54)
  • The special passive AUX distributors allow a power supply of max. 20 A to be passed through for actuators
