Модуль я использовал совместно с этим (EDC-279577) приёмником
Выводы D0,D1,D2,D3 подключил к разъёмам N1,N2,N3,N4 соответственно. Питание 5V взял от приёмника. При включении все реле втягиваются и горят все соответствующие светодиоды. А при нажатии любой из кнопок на пульте соответствующее реле и светодиод обесточиваются. Чтобы при включении реле были обесточены, необходимы уровни "1" на входах N1,N2,N3,N4. То есть между приёмником и релейным модулем нужно поставить инвертор. Например К561ЛН2 из отечественной базы. Питание у этой микросхемы от 3 до 15 вольт, так что будет в самый раз.
