SY 9223-Profibus Balun


Description

The  SY  9223  Profibus  balun  adapts a symmetrical  signal  to  a  coaxial  line. Usually twisted pairs with an impedance of approx.  120 ? are  used  to  transmit  the Profibus  signals.  The  SY 9223  Profibus can be applied to use an existing triaxial wiring.

 

The  symmetrical  side  has  a  screw terminal and the unsymmetrical side has a triaxial BNT-jack. The SY 9223 Profibus can be mounted to a DIN 50022 support rail with 35 mm base. Other housings and connectors  are  available  upon  request. When  needed  the  outer  braid  can  be connected to ground on pin 2 of the screw terminals.

 

To  transmit  video  signals  using  twisted pair cables the balun can be used in the other direction, too.
