Timer heavy duty power relays

Fixed or adjusable threshold, up to 4 changeover contacts.
All based on the D relay series housing and pinning.

  • CTD4 relay – Multifunction customizable timer, 4 pole

     Plug-in electronic 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…

  • FDA series, interval timer relay (flashing relay)

     Plug-in electronic pulsing relay with two change-over contacts, suitable for DC and AC coil voltage (50/60 Hz). When the relay is activated the coil starts with an interval. The pulse time and interval time are equal. The pulsing frequency is adjustable with a lockable knob. The relay can also be supplied with a fixed pulsing frequency (no knob). The relay is standard equipped with double zener diode coil protection. The…

  • TDBE4, dual function timer relay

     Plug-in industrial electronic 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. (more…)

  • TDDB series, delay-on timer relay

     Delay off timer relay for demanding applications, switching of AC & DC, voltages, resistive and/or inductive loads. Plug in 2CO contacts direct and 2 C/O contacts time delayed DC and AC coil Flash barriers LED indicator Cadmium free contacts ‘Smitt-style’ pinning with integrated retaining clip silver plated Adjustable with a lockable knob This relay is obsolete from January 1, 2023.

  • TDE4N relay – Timer, delay-off, 4 pole

     Plug-in electronic industrial timer relay with four change-over contacts. 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 a LED which indicates the presence of energizing voltage. Standard equipped with back EMF suppression. Optionally equipped…
