WDDE-U200 relay – Instantaneous 2 pole and one-shot 2 pole

Categories: , , ,

Description

Plug-in electronic railway one shot timer relay with two instantaneous change-over contacts and two one shot change-over contacts. When the relay is activated the one shot change-over contacts are activated with one 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 to indicate presence of power supply and energizing of the coil.
The construction of the relay and choice of materials make the WDDE-U200 /U300 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 WDDE-U200/U300 relay an easy and flexible solution to use.

Application

These relay series are designed for demanding rolling stock applications.
The WDDE-U200/U300 is used in applications where instantaneous contacts and contacts with one pulse in output are necessary.
