The unit has pairs for Interbus, Devicenet and Profibus units. It has mpedance characteristics from 100 to 150 ohms but a capacitance of 60pF/m or less for work between two conductors.
The unit is 0.25 square millimeters and works for linear resistance controls. The attenuation is at 4 or 16MHz to 25 or 50dB/km.
The Profibus pair works with these attenuation setups while a 0.34 square millimeter setup is made for conductors with a linear resistance less than 61 ohms per km.
