Device family

The EDS500 device family has been designed as multilayer switch and multi-purpose
communication device specifically for tasks of the process data communication. The devices
are employed for the data communication in future-oriented energy networks, for remote
meter reading, remote monitoring and control when feeding renewable energy into Smart
Grids.
The device have
• four Ethernet interfaces (IEEE 802.3) for LAN connections.
• Up to two SHDSL interfaces for data transmission via 2-wire-copper for distances up to 25
km with transmission rates between 192 and 15.000 kbps.
• Up to two pluggable optical transceivers for communication via optical fibre in SFP design
(small formfactor pluggable) for an easy installation of various transceivers and distances
of up to 180 km at 100 Mbps.
• up to 2 serial interfaces for configuration and / or for transmission of serial remote access
protocols.
The devices feature extensive management tools for telecontrol like Syslog, SNMP, SSH,
Telnet, IEC 60870-5-104 and an integrated web-server for easy configuration as well as
comprehensive self monitoring functions to monitor the signal quality on copper cables and
optical lines as well as the device status.
High availability operation is possible as redundant structures like rings or parallel routes can
be set up.
These features cut out the EDS500 devices as the ideal communications technology for
telecontrol technology e.g. according to IEC 60870-5-104, IEC 60870-5-101 or IEC 61850. Old
copper networks become high performance IP networks with telecontrol and redundant
protection. In a mixed operation it is possible to keep the old telecontrol technology while
adding modern technology step by step (TCP/IP based transmission, VoIP phones).
The compact housing without any moving parts for easy mounting on hat rails, a wide range
power supply (24 to 60 V DC), low power consumption, an enhanced temperature range and
integrated overvoltage protection prove the concept of the EDS500 devices.
