KDN-U200 relay - Latching, 8 pole
Summary
Description
Plug-in bistable railway relay with eight change-over contacts. The contacts remain in the last powered position, the position is clearly shown via a position indicator. Bistable by means of two coils and a mechanical rocker mechanism. The two separate coils are galvanically isolated.
Standard equipped with magnetic arc blow-out for high breaking capacity and long contact life. No external retaining clip needed as integrated ‘snap-lock’ will hold relay into socket under all circumstances and mounting directions.
The construction of the relay and choice of materials makes the KDN-U200 relay suitable to withstand low and high temperatures, shock & vibrating and dry to very humid environments.
Compact design, choice of many options and a wide range of sockets makes the KDN-U200 relay an easy and flexible solution to use.
Application
These relay series are designed for demanding rolling stock applications. The KDN-U200 is used in applications where eight contacts are used in one relay and the contacts are set and reset with permanent power or impulses.
