407 relay - Latching, safety critical, 40 contacts
Informatie
Description
The 407 is a latching relay with 2 stable magnetically latched states. When 1 coil is energized, the relay actuates from magnetically latched position 1 to 2. When the other coil is energized, the relay actuates back from magnetically latched position 2 to 1.
The Relay has 40 double break contacts (Form X & Y - per customers specification) in all N/O and N/C combinations and with weld no transfer feature as standard The plug-in design offers secure locking feature for maximum ease of maintenance (no wires need to be disconnected or other hardware removed for relay inspection or replacement).
The 407 relay can be plugged in the COR OU type socket.
Application
The 407 latching relay is especially build for double driver desk equipped locomtives and used to switch all controls of a drivers desk in a locomotive at once to the other driver desk on the other side of the locomotive. It is also used in track side applications to give the opportunity to install a new train control system. The relay can be used to commute during the night from an existing system to a new system. In that case the authorities allow the new contractor to work only during the night and for a limited number of hours. The relay saves time by eliminating the time consuming task of verifying each time the connection and disconnection of the existing system to the new system.
