Latching relays

KCS-U200 relay - Latching , 2 pole

Summary

Description

Bistable railway relay with two change-over contacts. The contacts remain in the last powered position. Bistable by means of two coils and a mechanical rocker mechanism. The two separate coils are galvanically isolated. The contacts are weld-no-transfer contacts: they are mechanically forced in the same position.
 
The KCS-U200 relay is a compact design relay connected with 2.8 x 0.8 mm fastons. The construction of the relay and choice of materials makes the KCS-U200 relay suitable to withstand low and high temperatures, shock & vibrating and dry to humid environments.
 

Application

These relay series are designed for demanding rolling stock applications. The KCS-U200 is used in applications where two contacts are used in one relay and the contacts are set and reset with permanent power or impulses.
