Description
The TCBBU 400 is a flashing relay with 4 double make / double break C/O contacts (form Z). The pulse duration is fully programmable with a dip switch from 0.25 s to 63.75 min. The access to dip switch is available by removing time delay cover. This feature prohibits frivolous field time delay setting.
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 TCBBU 400 relay 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.
