Popis
Plug-in bistable railway relay with eight change-over contacts, for reliable switching of very low currents (1 mA@5 VDC) up to currents of 10A @ 110VDC. 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.
The built-in magnetic arc blow-out ensures adequate DC breaking capacity resulting in long contact life. The integrated contact separation prevents cross pollution of contacts. On the relay cover the serial number and data matrix code are shown for ease of traceability.
The construction of the relay and choice of materials make the KDN-U200N relay suitable to withstand corrosive atmospheres, low and high temperatures, shock & vibrating and dry to humid environments. No external retaining clip needed as integrated ‘snap-lock’ will hold relay into socket under all circumstances and mounting orientations.
Compact design, choice of many options and a wide range of sockets makes the KDN-U200N relay an easy and fl exible solution to use
Application
The KDN-U200N can be used in demanding rolling stock applications where eight contacts are used in one relay and the contacts are set and reset with permanent power or impulses.
