ub-content-link--unknown ub-content-link--status-after\"><a rel=\"noreferrer noopener\" href=\"https:\/\/www.fambach.net\/preview-esp01-relais-modul\/\" target=\"_blank\" class=\"ub-content-link__anchor\"><strong>Link<\/strong> zum Beitrag<\/a><span class=\"ub-status ub-status--unknown\" title=\"Link status: Unknown\"><span class=\"ub-status__icon\" aria-hidden=\"true\">\u25cf<\/span><span class=\"screen-reader-text\">Link status: Unknown<\/span><\/span><\/span>). Es handelt sich hierbei um eine Platine mit einem Steckplatz f\u00fcr den ESP01 und einem Relais zum Schalten einer externen Spannung. \u00c4hnliche Platinen gibt es nun auch mit zwei, vier, acht oder mehr Relais. Geschaltet werden kann eine externe Wechselspannung bis zu 250V oder eine Gleichspannung von max. 30V. Beim schnellen Ali fangen die Platinen bei rund 6\u20ac f\u00fcr die 2-Relais-Version an.  <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Die 1-Relais-Version wird direkt \u00fcber den GPIO0 geschaltet. Wegen der begrenzten IOs des ESP01 funktionieren die Mehr-Relais-Versionen etwas anders, sie besitzen noch einen STM8-Prozessor zur Ansteuerung der Relais. Dieser kann, durch kurze Nachrichten auf dem seriellen Bus, die Relais schalten. Warum hier kein I\u00b2C-Portexpander verwendet wurde, kann ich nicht verstehen, w\u00e4re bestimmt zu einfach gewesen ;).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Noch etwas f\u00e4llt auf: Bei der Ein- und Zwei-Relais-Version ist keine galvanische Trennung zwischen Steuer- und Relaisstromkreis (au\u00dfer \u00fcber das Relais selbst). Die 4-Relais-Version besitzt Optokoppler zum Schalten und auch Aussparungen in der Platine, um Spannungs\u00fcberspr\u00fcnge zu vermeiden. Wie bei allen China-Produkten ist bei der Verwendung von hohen Spannungen mit Vorsicht zu agieren.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"fakten\"><span class=\"ez-toc-section\" id=\"Fakten\"><\/span>Fakten<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table id=\"wpls-table-1\"><thead><tr><th><strong>Beschreibung<\/strong><\/th><th><strong>Wert<\/strong><\/th><\/tr><\/thead><tbody><tr><td>Baudrate<\/td><td>115200 (evtl. auch 9800, bei mir waren es die 11)<\/td><\/tr><tr><td>Steckplatz ESP01<\/td><td>1<\/td><\/tr><tr><td>Relais<\/td><td>1- \u2026. die von mir gr\u00f6\u00dfte hatte 16 Relais<\/td><\/tr><tr><td>Versorgungsspannung<\/td><td>5V<\/td><\/tr><tr><td>Schaltspannung<\/td><td>10\u00a0A\/250VAC; 10\u00a0A\/30VDC<\/td><\/tr><\/tbody><\/table><figcaption class=\"wp-element-caption\">Grunds\u00e4tzliche Daten<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table id=\"wpls-table-2\"><thead><tr><th><strong>Beschreibung<\/strong><\/th><th>1 Relais<\/th><th>2 Relais<\/th><th>4 Relais \u2026 <\/th><\/tr><\/thead><tbody><tr><td>Relais 1 Schalten<\/td><td>GPIO0<\/td><td>An A0 01 01 A2<br>Aus A0 01 00 A1<\/td><td>An A0 01 01 A2<br>Aus A0 01 00 A1<\/td><\/tr><tr><td>Relais 2 Schalten<\/td><td>\u2013<\/td><td>An A0 02 01 A3<br>Aus A0 02 00 A2<\/td><td>An A0 02 01 A3<br>Aus A0 02 00 A2<\/td><\/tr><tr><td>Relais 3 Schalten<\/td><td>\u2013<\/td><td>\u2013<\/td><td>An A0 03 01 A4<br>Aus A0 03 00 A3<\/td><\/tr><tr><td>Relais 4 Schalten<\/td><td>\u2013<\/td><td>\u2013<\/td><td>An A0 04 01 A5<br>Aus A0 04 00 A4<\/td><\/tr><tr><td>Schalter 1<\/td><td>\u2013<\/td><td>Moduswahlschalter<\/td><td>Moduswahlschalter<\/td><\/tr><tr><td>Schalter 2<\/td><td>\u2013<\/td><td>Zur\u00fccksetzen auf Auslieferzustand<\/td><td>Zur\u00fccksetzen auf Auslieferzustand<\/td><\/tr><\/tbody><\/table><figcaption class=\"wp-element-caption\">Beschaltung der Relais<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table id=\"wpls-table-3\"><thead><tr><th>Pin Name<\/th><th>Beschreibung<\/th><\/tr><\/thead><tbody><tr><td>NC \u2013 Normal Closed<\/td><td>Im Ruhezustand geschlossen \/ \u00f6ffnet mit Aktivierung des Relais<\/td><\/tr><tr><td>COM \u2013<\/td><td>Schaltspannung der Relais wird an die anderen Kontakte durchgereicht bis zu 30V DC \/ 240V AC<\/td><\/tr><tr><td>NO \u2013 Normal Open<\/td><td>Im Ruhezustand ge\u00f6ffnet \/ schlie\u00dft mit Aktivierung des Relais<\/td><\/tr><\/tbody><\/table><figcaption class=\"wp-element-caption\">Relais Beschriftung<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<figure class=\"wp-block-table\"><table id=\"wpls-table-4\"><thead><tr><th>Startwert Fix<\/th><th>Relais<\/th><th>Schaltwert<\/th><th>Checksumme<\/th><\/tr><\/thead><tbody><tr><td>A0<\/td><td>01-04<\/td><td>01 = AN<br>00 = Aus<\/td><td>A+Summe aus Relais und Schaltwert<br><br>Beispiel: Relais 1 = An<br>(Relais) 01+ (An) 01 = 2<br>=&gt; Checksumme = A2<br><br>Beispiel2: Relais 4 = Aus<br>(Relais) 04+ (Aus) 00 = 4<br>=&gt; Checksumme = A4<\/td><\/tr><\/tbody><\/table><figcaption class=\"wp-element-caption\">Telegrammformat, Daten m\u00fcssen in Hex \u00fcbertragen werden.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"anwendungsbereiche\"><span class=\"ez-toc-section\" id=\"Anwendungsbereiche\"><\/span>Anwendungsbereiche<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Hausautomation<\/li>\n\n\n\n<li>Abh\u00e4ngige Schaltvorg\u00e4nge<\/li>\n\n\n\n<li>Automation<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"ansichten\"><span class=\"ez-toc-section\" id=\"Ansichten\"><\/span>Ansichten<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-2 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.fambach.net\/wp-content\/uploads\/ESP01RelaisModul-topWithESP01.jpg\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"444\" data-id=\"8965\" src=\"https:\/\/www.fambach.net\/wp-content\/uploads\/ESP01RelaisModul-topWithESP01.jpg\" alt=\"\" class=\"wp-image-8965\" srcset=\"https:\/\/www.fambach.net\/wp-content\/uploads\/ESP01RelaisModul-topWithESP01.jpg 600w, https:\/\/www.fambach.net\/wp-content\/uploads\/ESP01RelaisModul-topWithESP01-300x222.jpg 300w, https:\/\/www.fambach.net\/wp-content\/uploads\/ESP01RelaisModul-topWithESP01-16x12.jpg 16w\" sizes=\"auto, (max-width: 599px) calc(100vw -
