Information about planning and application
Transmission ranges
With regard to the transmission ranges of the voltage transmission there are generally no
further restrictions. Here, too, the maximum cable length between two devices must nor exceed
100 m.
However, it should be noted that a Cat 5e cable exhibits a higher generation of heat due to its
low cable cross section. This can, among others, have a negative effect on the reachable
transmission range.
Compatibility (with foreign devices)
The ABB-Welcome IP devices are exclusively compatible with standardised PoE versions.
