class=\"wp-block-paragraph\">Wieder mal ein Mysterium von einer Zusatzplatine. Es gibt zwar viele Seiten,\u00a0welche diese Platine verkaufen, ich habe aber nur genau ein Video und ein Testbeispiel gefunden, das ist mir auch noch nicht passiert.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Die Platine besitzt 4 Relais, die \u00fcber die Pins 4-7 geschaltet werden k\u00f6nnen. Die Relais k\u00f6nnen laut Reichelt mit bis zu 240V Wechselspannung belastet werden. In Anbetracht der fehlenden Isolierung der Platine, und dass hier gerade mal 1,5 Ampere m\u00f6glich sind, w\u00fcrde ich aber davon abraten.  F\u00fcr 12V bis 24V Gleichspannung eignet sie sich hingegen ganz gut. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Thanks to <span class=\"ub-content-link ub-content-link--ok ub-content-link--status-after\"><a href=\"https:\/\/www.youtube.com\/redirect?redir_token=N9_Zchcj_yXScNFpNhTjWgkgv4t8MTU2MDM2NDg3NEAxNTYwMjc4NDc0&amp;q=http%3A%2F%2Frobojax.com%2Flearn%2Farduino&amp;v=u9q6cHj89b4&amp;event=video_description\" target=\"_blank\" rel=\"noreferrer noopener\" class=\"ub-content-link__anchor\">http:\/\/robojax.com\/learn\/arduino<\/a><span class=\"ub-status ub-status--ok\" title=\"Link status: OK\"><span class=\"ub-status__icon\" aria-hidden=\"true\">\u25cf<\/span><span class=\"screen-reader-text\">Link status: OK<\/span><\/span><\/span> for the video and the example.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"ansicht\"><span class=\"ez-toc-section\" id=\"Ansicht\"><\/span>View<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Die Ansicht von oben zeigt links die Anschlussklemmen f\u00fcr Relais 1 und 2.\u00a0In der linken unteren Ecke befinden sich die Anschlussklemmen f\u00fcr Relay 3\/4.
