SY 9223 Profibus

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

SY 9223-7637-4

 

SY 9223-7637-4 is a symmetrical transformer (balun, balance-to-unbalance transformer). It transforms an unsymmetrical RF signal into a symmetrical one while not transforming the impedance. It has low insertion loss, a wide range of bandwidth and can dissipate a big amount of power.

 

 

Frequency range:  100 kHz ... 30 MHz
Useable frequency range:  9 kHz ... 50 MHz
Impedanz:  50 Ω nominal
Continuouse power dissipation:  100 W
Impedance ratio:  1:1

Operating voltage:  750 Vrms @ 60 Hz
Insertion loss:  <0.2 dB
Amplitude unbalance:  <0.5 dB
Common mode rejection:  >40 dB @ 1 MHz
Connector symmetric:  4 mm safety laboratory jack
Connector unsymmetric:  N-jack, 50 Ω
Length:  140 mm
Width:  105 mm
Height:  50 mm
Weight:  ca. 0.5 kg
