Plug-in electronic railway timer relay with four change-over contacts for reliable switching of very low currents (1 mA @5 VDC) up to currents of 10A @ 110VDC. 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 one LED which indicates the presence of power supply.

The built-in magnetic arc blow-out ensures adequate DC breaking capacity resulting in long contact life. The integrated contact separation prevents cross pollution of contacts. On the relay cover the serial number and data matrix code are shown for ease of traceability.

The construction of the relay and choice of materials makes the TDE4N-UN relay suitable to withstand low and high temperatures, shock & vibration and dry to humid environments.

No external retaining clip needed as integrated ‘snap-lock’ will hold relay into socket under all circumstances and mounting orientations.

Compact design, choice of many options and a wide range of sockets makes the TDE4N-UN relay an easy and flexible solution to use.
