Signal Transmission
The possible transmission distance is essentially determined by the highest occurring signal
frequency, the properties of the transmission line and the input of the connected receiving
device.
When connected to our Isolating Barrier D461R1
…
, a signal frequency of 25000 Hz can be
safely transmitted over a distance of up to 500 m. If the signal frequency is lower, a corres-
pondingly longer transmission distance applies. The cable is based on a 3-core or 4-core
shielded version LiYCY or LiTCT with 3x0.5 mm
2
or 4x0.5 mm
2
, as supplied by us (R <36 Ohm /
km, C <150 pF / m).
The signal frequency in Hz is calculated with a uniformly divided profile by:
Number of poles x speed / 60.
For narrow poles, the effective frequency must be set higher in accordance with the relationship
between pole and gap.
Important in the transmission:
A continuous good shielding must be provided. The shield must be connected directly to a shield
rail on the receiving side. Never transmit multiple signals under one common screen!
Lay transmission line separately from sources of interference.
