Description
The BG 400 relay has 4 double make / double break C/O contacts (form Z). The contacts are gold plated on hart silver. This relay is used when dry circuits route to socket are not identified.
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 resistance to impact and vibration is conform to standards in force for Railway Transported Equipment.
Positive mechanical keying of relay to socket is built into relay and socket during manufacture and terminal identifications are clearly marked on identification plate that is permanently attached to the relay.
The BG 400 relays is pluggable in the following sockets: EA 102 B, EA 102 BF, EA 103 BF, EA 104 B, EA 104 BF, EA 105 BF, EA 112 BF.
Application
The BG 400 relay is designed for low level signals switching in dry circuit signal information. The relay is equipped with a contact pollution barrier in case of mixed load operation for ultra reliable heavy duty and safety critical applications such as door control, emergency brake failure, interlocking between traction and breaking, around the world in countless railcars.
