Relays

We offer a wide range of highly reliable relays for on-board and trackside applications. All the relays are designed by railway engineers to outlive the life time of a train.

Instantaneous relays

The contacts of an instantaneous relay pull-in when the coil is energized and drop-out when the coil voltage is off.

D-U200 instantaneous relay with 4 contacts

  • Compact plug-in design
  • Instantaneous, 4 CO contacts
  • Standard back EMF diode
  • Magnetic arc blow-out.
  • Flat, square silver plated relay pins for excellent socket connection
  • Wide range sockets
  • Integrated snap lock
  • Transparent cover

Latching relays

The contact of a latching relay pull-in with a voltage pulse is applied on the coil and drop-out with another pulse. This can be done by using two coils assisted by a mechanical or magnetic locking mechanism.

Timer relays

Time delay have additional electronic circuits, creating specific timing functions of the contacts.
