SY 9223 Profibus Balun 

Schwarzbeck SY 9223 Profibus Balun

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.

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
