310 relay - Latching, safety critical, 18 contacts

Informatie

Description

The 310 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. Relays have 18 double break contacts (Form X & Y - per customer specification) in all N/O and N/C combinations.
 
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. Weld no transfer safety contacts are standard. If one N/O contact welds, no N/C contact can close and visa versa. All relays are factory tested to insure they meet this important safety requirement.
 

Application

The 310 latching relay allows the memory of the state of the circuit in case of power interuption. Optional gold contact are possible for dry circuit applications or silver and gold contacts combined for mixed load applications.
