Plug-in electronic railway timer relay with three change-over contacts and delay-off function. The relay is energized by auxiliary supply and activated by an external N/O contact. The delay time is adjustable with a lockable knob. The relay can also be supplied with a fixed time delay (no knob). The relay is equipped with two LEDs which indicate the presence of power supply and the energizing of the coil. 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 TDE3-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 TDE3-U200 relay an easy and flexible solution to use.


These relay series are designed for demanding rolling stock applications. The TDE3-U200 is used in applications where a time delay on drop-out is necessary.
