Railways applications - Direct current signalling relays

This European Standard gives requirements for direct current relays intended for safety-related applications in railway signalling installations. This European Standard is applicable to monostable relays. However it can also be used as a guide for other relays such as with bistable relays.

Bahnanwendungen - Gleichstrom-Signalrelais

Applications ferroviaires - Relais de signalisation à courant continu

Železniške naprave - Enosmerni signalni releji

Ta evropski standard podaja zahteve za enosmerne signalne releje, namenjene za varnostne priprave v signalnih železniških napravah. Ta evropski standard velja za monostabilne releje. Vendar pa se lahko uporablja tudi kot vodilo za druge releje, kot so bistabilni releji.

This European Standard was approved by CENELEC on 2013-05-20. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the CEN-CENELEC Management Centre or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the CEN-CENELEC Management Centre has the same status as the official versions.
