Panel-mounted fault annunciator
USS/USM series Elektra Elektronik GmbH & Co. Störcontroller KG


  • Options:



The USM is based on the BSM-P in general functionality. For communication with superior or inferior systems the USM is equipped with one or two communication cards. The interfaces and can so be driven via protocols like IEC 60870-5-101 or IEC 60870-5-104 with up to 4 clients (multilink) as well as per IEC 61850 with external systems. It is possible to combine different of the above mentioned protocols within one annunciator. Additionally the USM provides an integrated web-server, which guarantees the parameterization via network with all current web-browsers. All annunciator and interface parameters are available on the web-server and can be parameterized through it. Additional software or special cables are not required. Service-access and online-monitoring complete the functions provided by the integrated web-server. Labelling of the annunciator is done by means of designation strips that can be inserted beneath the cover foil after removing the front frame. They can be created and printed directly from the parameterisation interface or generated manually from labelling strips in Word-format. An optionally integrated relay card or a redundant power-supply increase the fault annunciator and therefore can be used for higher-value demands.
