Timer relais

TDE4N-U relay - Timer, delay-off, 4 pole

Informatie

Description

Plug-in electronic railway timer relay with four change-over contacts. When the relay is de-energized there is a delay on drop-out without any auxiliary power supply. 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 a LED which indicates the presence of energizing voltage. Standard equipped with back EMF suppression and magnetic arc blow-out for high breaking capacity and long contact life.
 
The construction of the relay and choice of materials makes the TDE4N-U 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 TDE4N-U relay an easy and flexible solution to use.
 

Application

These relay series are designed for demanding rolling stock applications. The TDE4N-U is used in applications where a time delay on drop-out is necessary after de-energizing the relay, without using auxiliary supply.
