TDDB-U300 relay – Timer, delay-on, AC input, delay on 4 pole

Categories: , , ,

Description

Plug-in electronic railway timer relay with two instantaneous change-over contacts and two time delayed change-over contacts. When the relay is activated there is a delay on pull-in for the time delayed contacts. 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 to indicate presence of power supply and energizing of the coil.
The construction of the relay and choice of material makes the TDDB-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 TDDB-U200/U300 relay an easy and flexible solution to use.

Application

These relay series are designed for demanding rolling stock applications.
The TDDB-U200/U300 is used in applications where instantaneous contacts and contacts with a time delay are necessary.
