About this item

  • The module can be high or low by a jumper setting trigger
  • With patch optical isolation, strong drive ability and stable performance
  • fault-tolerant design, even if the control line is defective, the relay will not operate
  • Can set high or low level trigger with jumper to meet the demand of more trigger applications
  • Interface design humane, all interfaces can be connected directly via terminal wiring leads, very convenient

    Reviewed in Italy on 2 May 2019

    Utilizzati per modificare un telecomando per stufa a pellet interfacciandolo con un interruttore orario programmabile con in cascata questo modulo.
    I due relè sono risultati necessari per ottenere la chiusura per qualche secondo del relè usato come uscita sia all'inserimento del timer sia al successivo disinserimento, cosa realizzata collegando in cascata i due relè tramite un gruppo RC.
    Circuito perfettamente funzionante, e relativa condizione ottimamente segnalata dai due led che indicano l'eccitazione dei rispettivi relè e da un terzo led che indica la presenza dell'alimentazione a 12 VDC.
    Interessante la possibilità di comando sia con segnali positivi che negativi.
    Come al solito un perfetto servizio Amazon con consegna molto veloce.

    Ottimo prodotto di facile installazione ed utilizzo
    Come per tutte queste schede a relais, ricordarsi di settare adeguatamente i due jumper (uno per ciascun canale) in modo da rispettare la funzionalità della scheda di comando che si utilizza per pilotare i relais.
    Consigliatissimo anche per il rapporto qualità/prezzo

    2.0 out of 5 stars Relais hängen beim abschalten.
    Reviewed in Germany on 4 January 2019
    Verified Purchase
    Einsatzzweck, 12V trigger des AVR zu nutzen um Steckdosen zu schalten für eine digitale X-over plus Amp bzw das Netzteil meines fire tv Stick.
    Theoretisch klappt das gut, gelegentlich bleiben die Relais aber hängen so das die Steckdosen nicht abgeschaltet werden.

    Einzige Hilfe dann, auf die Relais klopfen dann fallen sie ab. Doof nur wenn diese tief im Rack liegen hinter einer Blende.

    Daher für die Zuverlässigkeit die Sterne Abzug.
