FDC4-U200 relay – Flashing, 4 pole


Plug-in electronic railway flashing timer relay with four change-over contacts. When the relay is activated the coil is energized with a pulse. The pulse time is adjustable with a lockable knob.
The relay can also be supplied with a fixed pulse time (no knob). The relay is equipped with two LEDs which indicate the presence of power supply and the energizing of the coil. Also 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 FDC4-U200 relay suitable to withstand low and high temperatures, shock & vibration 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 FDC4-U200 relay an easy and flexible solution to use.


These relay series are designed for demanding rolling stock applications. The FDC4-U200 is used in applications where an asymmetrical pulse frequency in output is necessary after activating the relay.
