Timer relais

WDE4-U200 relay - Timer, one-shot, 4 pole

Informatie

Description

Plug-in electronic railway one-shot timer relay with four change-over contacts. When the relay is activated the coil is energized with one pulse. The pulse time is adjustable with a lockable knob. The relay can also be suplied 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 contacts. 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 WDE4-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 WDE4-U200 relay an easy and flexible solution to use.
 

Application

These relay series are designed for demanding rolling stock applications. The WDE4-U200 is used in applications where one pulse in output is necessary after activating the relay.
