Summary

Description

Plug-in electronic railway timer relay with delay-on and delay-off function and three change-over contacts and one normally-closed contact. The delay times are independently adjustable with two lockable knobs. The relay can also be supplied with one or two fixed delay times (one knob or none). The relay needs an auxiliary supply and can be activated with an external N/O contact or with AC or DC supply voltage.

The relay is equipped with two LEDs which indicate the presence of power supply and the energizing of the coil. 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 TDBE4- U200/300 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 TDBE4-U200/300 relay an easy and flexible solution to use.

Application

These relay series are designed for demanding rolling stock applications. The TDBE4-U200/300 is used in applications where a delay on pull-in and on drop-out is necessary.
