Popis
Plug-in electronic railway one-shot relay with three change-over contacts. The relay is activated by the negative going edge of a DC voltage on the input terminals. The pulse time is fixed and standard 3 seconds, other pulse times on request.
The relay has two LEDs which indicate the presence of power supply and contact switching. Standard equipped with magnetic arc blow-out for high breaking capacity and long contact life.
The construction of the relay and choice of materials makes the PDF3-U200 relay suitable to withstand 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 directions.
Compact design, choice of many options and a wide range of sockets makes the PDF3-U200 relay an easy and flexible solution to use.
Application
These relay series are designed for demanding rolling stock applications. The PDF3-U200 is used in applications where the relay must be activated for a fixed time when the voltage on the input terminals drops to zero.
