Ethernet-to-RS485/RS422 Gateway
The D502 is an easy to configure Ethernet-to-RS485/RS422 gateway. It provides up to two RS485/RS422 interfaces (SER0 / SER1) as well as up to two 10/100 Mb/s Ethernet interfaces (ETH0 / ETH1). The Ethernet connectors comply with IEC 61076-2-101 (D-coded; female).
The Ethernet interfaces comply with IEEE 802.3 supporting 10BASE-T or 100BASE-TX, full duplex mode, auto-negotiation and auto MDI-X. Furthermore, the internal logic supports the "Ethernet on traction vehicles" standard IEC 61375-3-4.
Variety of Product Options
The optional second Ethernet interface ETH1 is intended to be used as a redundant line or as a separate channel for remote diagnostic and maintenance purposes.
duagon's gateways are available in two variants – as platform to build a customer-specific application or as gateway with a standard configurable gateway application. The platform variant is accompanied by a development library that enables fast and efficient design of customer-specific applications.
The gateway is integrated in a stainless-steel housing that can be mounted on a DIN rail or using M4 screws. The device can be powered directly from the vehicle battery or by Power over Ethernet (PoE).
For Rolling Stock Environments
The D502 is designed for harsh rolling stock environment and complies with the EN 50155, EN 50121, and IEC 61373 standards: it withstands -40 °C to +70 °C ambient temperatures, complies with interruption voltage supply class S2, is coated against humidity and provides enhanced EMI and vibration robustness.
