Mors Smitt offers a wide range of highly reliable relays for on-board and trackside applications.
All our relays are designed by railway engineers to outlive the life time of a train.
Up to date more than 10 million relays are installed world wide.
The contacts of an instantaneous relay pull-in when the coil is energized and drop-out when the coil voltage is off.
Time delay have additional electronic circuits, creating specific timing functions of the contacts.
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 asisted by a mechanical or magnetic locking mechanism.
Monitoring relays have built in switching points, to monitor accurately specific input voltages or currents.
