EES USM Networkable Fault Annunciators

The networkable annunciators of the series USM provide the functionality and flexibility of the series BSM and adds communication interfaces for connection to both superior and inferior systems. Through the Modbus protocol information or states can be exchanged and through IEC 60870-5-101/104 and IEC 61850 single and double alarms can be transmitted e.g. to a SCADA system and single and double commands can be received and issued from the annunciator. In the download area cost-free available EPLAN macros facilitate the creation of circuit diagrams and a smart parameterisation concept ensures that installation and commissioning of the interfaces is easy as never before!

Overview of specifications:
– 8 / 16 / 24 / 32 / 40 / 48 signal inputs with corresponding LED display
– Integrated logic for assignment of in- and outputs
– Ethernet-interface with communication protocols IEC 61850 and/or IEC 60870-5-104
– Serial interface with communication protocol IEC 60870-5-101
– Realisation of redundant communication structures by means of Multilink and multiple interfaces

Web-Server Parameterisation:
All parameters for processing and display of alarms as well as protocol-specific settings can be easily and intuitively configured with the Web-Server through the use of Drag & Drop and parameter import from Excel.

Online Monitoring:
With the respective IP-address, you can monitor your sites at all times.

IEC 60870-5-101 / 104 interface:
Alarms from the USM can be transmitted from the field directly to the SCADA or telecontrol systems. With the use of standardised telecontrol protocols acc. To IEC 60870-5-101 / 104, more cabling works can be saved compared to conventional solution with forwarding relays.

IEC 61850 interface:
This interface allows the integration of fault annunciators into station automation for medium and high voltage stations. The annunciator is able to gather signals through its galvanic inputs and provide single point information and collective reports on the IEC 61850 bus.
