Introduction
The ToughNet TN-4100 Series M12 ETBN repeaters are EN
50155-certified devices designed for harsh industrial and railway
rolling stock environments. By regenerating both Ethernet frame data
and electrical signal characteristics, the TN-4100 Series enables
Ethernet segment extension beyond the standard 100-meter limit. In
accordance with IEC 61375-2-1, these repeaters are installed between
Ethernet train backbone nodes (ETBNs) to provide transparent link
extension, ensuring stable communication across extended vehicle consist
lengths, such as articulated or multi-car trains.
The TN-4100 Series combines two
isolated IEC 61375 ETBN repeaters into a single compact housing to
save installation space and simplify system deployment. Equipped with
four M12 ports featuring IEC 61076-010 inner-locking push-pull connectors
and DIP switch configuration, these repeaters ensure tight, robust
connections and offer complete protocol transparency for train communications,
including TTDP and TRDP.
All
TN-4100 Series models support an extended operating temperature range
of -40 to 70°C and fully comply with the mandatory requirements of
the EN 50155 standard, including temperature, power input range, surge,
ESD, and vibration resistance. Additionally, the TN-4100 Series features
a single isolated power module with dual 24 to 110 VDC power inputs
and integrated relay alarm outputs to ensure high availability, scalable
network design, and uninterrupted on-board operations.
