KISSLING Bistable Industrial Relays

KISSLING Series 31

Latching relays are also known as bistable relays since they have two relaxed states. Only a voltage pulse will activate the bistable relay to pull in or release the contacts and it will hold its contact position till the next voltage pulse. Since no continuous current must be applied to change the switching state the bistable relays are generating less heat than monostable relays. They can then conduct a higher continuous current than monostable relays. Bistable relays are used in applications where power must be conserved since they can maintain their contact position during power interruptions.

KISSLING Bistable Relays

Series 31

Our Series 31 offering includes power relays in nominal voltages of 12 & 24 V and nominal continuous amperages of from 200 Amps to 300 Amps. It features electronic functions for pulse protection of the coil, a low energy switching input for direct connection to an ECU, as well as an optional "energy" function for fail-safe shutoff when power is lost. 

 

Other important advantages include a two-pin coil control which allows this relay to serve as a drop-in replacement for a mono-stabile relay in an application where the power drain of a mono-stabile relay is an issue. The electronic functions directly coupled to the relay not only reduce peripheral circuitry and costs in the vehicle itself but also improves safety levels in critical switching applications. 

 

The bistable relays Series 31 are particularly well suited for battery management and power distribution applications on commercial vehicles, buses, construction and agricultural vehicles, aircraft, ground support equipment and lift trucks. 
Detailed information regarding the various types is available on request. Custom relays can be developed in accordance with your specifications.
