SB relay - Latching, 4/3 contacts
Informatie
Description
The SB is a latching safety critical 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.
Two types of configuration are available:
- 400 type contact relays have 4 changeover double break contacts (Form Z)
- 300 type contact relays have 3 changeover double break contacts (Form Z) a 4th double break contact is reserved for automatic coupling of the coils.
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.
Application
The SB latching relay allows the memory of the state of the circuit in case of power interruption.
