Compact Ethernet Solution for Railway Applications
The D512 is a compact 2-port Ethernet repeater for railway applications that is completely transparent to all Ethernet protocols and offers full 10/100 Mbit bandwidth in full or half duplex mode. It allows the integration of any remote device or sub-network into an Ethernet network, and with its low latency, it is ideal to bridge long distances in redundant ring topologies.
Optionally it is available with bypass relays. In the case of bypass relays, there is a digital status output pin available.
High-Speed, Robust Connectivity for Long Distances
The D512 is intended to enable 10BASE-TX or 100BASE-TX connections of more than 100 meters (for connections with a high number of connectors and/or long patch cables the limit is even less than 100 meters).
The two Ethernet ports support 10BASE-TX or 100BASE-TX, auto-crossover and auto-negotiation. They are equipped with M12 connectors to guarantee a reliable connection.
As an option, the repeater can be ordered with a customer defined configuration for the Ethernet ports, with auto-negotiation and autocrossing on by default.
For Rolling Stock Environments
The D512 is designed for harsh rolling stock environment and fully compliant to EN 50155, IEC 61375 and IEEE 802.3. It withstands -40 °C to +70 °C ambient temperature, is coated against humidity and provides enhanced EMI and vibration robustness.
D512 is powered directly by the train battery (24 V to 110 V) or by PoE (IEEE 802.3af).
