Summary

Description

Plug-in electronic railway timer relay with four 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 timer relay has a fixed customer specified delay time, but can also be supplied with an adjustable delay time (with lockable knob). The delayed contacts are weld no transfer contacts. The relay is equipped with two LEDs which indicate the presence of power supply and the energizing of the time delayed contacts.

The construction of the relay and choice of materials makes the TDD4B2-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 TDD4B2-U200 relay an easy and flexible solution to use.

Application

These relay series are designed for demanding rolling stock applications. The TDD4B2-U200 is used in applications where both instantaneous contacts and time delayed contacts are necessary.
