Timer relais

CTD4-U relay - Multifunction customizable timer, 4 pole

Informatie

Description

Plug-in electronic railway customizable timer relay with four change-over contacts. Fully customizable according customer’s requirements concerning timing diagram and delay type. Almost any timing diagram is possible: for example time delays with delay on pull-in, on drop-out or both, symmetrical or asymmetrical flashing, 1-shot, 2-shot, 3-shot etc. or a combination of all these. Delay/pulse times are adjustable with 1 or 2 lockable knobs. The relay can also be supplied with fixed delay/pulse times (no knobs).
 
The relay has standard four change-over contacts which work according the timing diagram. Also 2 instantaneous change-over contacts and 2 timer change-over contacts are possible, to cover virtually all needs. Besides being activated by a voltage level, it is possible to activate the relay via a command input as well. The relay is equipped with two LEDs which indicate the presence of power supply and energizing of the coil. Also 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 CTD4-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.
 
 

Application

These relay series are designed for demanding rolling stock applications. The CTD4-U relay can be used in all Railway applications where a standard or non-standard timer function is necessary.
