This HAT features eight relays, each capable of handling 4A at 120VAC or 24VDC, providing robust control for various applications. The relays are equipped with both normally open and normally closed contacts, along with LED indicators for easy status monitoring.\u003c\/p\u003e\n\n\u003cp\u003eThis stackable HAT can be layered up to eight times, allowing for a total of 64 relays, making it suitable for complex projects requiring extensive relay control. It includes an RS485 port and supports integration with command line interfaces, Python, and Node-RED, offering flexibility for developers and hobbyists alike. The HAT also supports Home Assistant and OpenPLC, and includes a CODESYS driver, enhancing its utility in automation and control systems.\u003c\/p\u003e\n\n\u003cp\u003eThe board is designed to use only the I2C port, leaving all GPIO pins available for other uses. It features pluggable connectors compatible with 26-16 AWG wires, ensuring secure and reliable connections. The inclusion of a general-purpose push-button and software self-test capabilities further enhances its functionality and ease of use.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cbutton class=\"expandable-content__toggle\" aria-expanded=\"false\" aria-controls=\"main-description\"\u003e\u003cspan class=\"expandable-content__toggle-icon\"\u003e\u003c\/span\u003e\u003cspan class=\"expandable-content__toggle-text\" data-view-more=\"View more\" data-view-less=\"View less\"\u003eView more\u003c\/span\u003e\u003c\/button\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003cdiv class=\"card details_product\"\u003e\n\u003cbutton class=\"card__collapsible-button\" data-action=\"toggle-collapsible\" aria-expanded=\"false\" aria-controls=\"unique-tab-2\"\u003e\r\n\u003cspan class=\"card__title heading h3\"\u003eWhat's Included\u003c\/span\u003e\r\n\u003cspan\u003e\r\n\u003csvg focusable=\"false\" class=\"icon icon--arrow-bottom\" viewbox=\"0 0 12 8\" role=\"presentation\"\u003e\r\n\u003cpath stroke=\"currentColor\" stroke-width=\"2\" d=\"M10 2L6 6 2 2\" fill=\"none\" stroke-linecap=\"square\"\u003e\u003c\/path\u003e\r\n\u003c\/svg\u003e\r\n\u003c\/span\u003e\r\n\u003c\/button\u003e\r\n\u003cdiv id=\"unique-tab-2\" class=\"card__collapsible\"\u003e\r\n\u003cdiv class=\"card__collapsible-content\"\u003e\r\n\u003cdiv class=\"rte text--pull\"\u003e\r\n\u003cul\u003e\n\t\u003cli\u003e1x Sequent Microsystems 8 Relays 4A\/120V 8-Layer Stackable HAT for Raspberry Pi\u003c\/li\u003e\n\t\u003cli\u003eMounting hardware\u003c\/li\u003e\n\t\u003cli\u003e4x M2.5x18mm male-female brass standoff\u003c\/li\u003e\n\t\u003cli\u003e4x M2.5x5mm brass screw\u003c\/li\u003e\n\t\u003cli\u003e4x M2.5 brass nut\u003c\/li\u003e\n\t\u003cli\u003eConnector plugs\u003c\/li\u003e\n\u003c\/ul\u003e\n\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\r\n\u003c\/div\u003e\n\u003c\/div\u003e\u003cdiv class=\"card details_product\"\u003e\n\u003cbutton class=\"card__collapsible-button\" data-action=\"toggle-collapsible\" aria-expanded=\"false\" aria-controls=\"unique-tab-3\"\u003e\r\n\u003cspan class=\"card__title heading h3\"\u003eDimensions\u003c\/span\u003e\r\n\u003cspan\u003e\r\n\u003csvg focusable=\"false\" class=\"icon icon--arrow-bottom\" viewbox=\"0 0 12 8\" role=\"presentation\"\u003e\r\n\u003cpath stroke=\"currentColor\" stroke-width=\"2\" d=\"M10 2L6 6 2 2\" fill=\"none\" stroke-linecap=\"square\"\u003e\u003c\/path\u003e\r\n\u003c\/svg\u003e\r\n\u003c\/span\u003e\r\n\u003c\/button\u003e\r\n\u003cdiv id=\"unique-tab-3\" class=\"card__collapsible\"\u003e\r\n\u003cdiv class=\"card__collapsible-content\"\u003e\r\n\u003cdiv class=\"rte text--pull\"\u003e\r\n\u003cp style=\"text-align: center;\"\u003e\u003cimg style=\"width: 600px;  \" alt=\"Eight Relays 4A\/120V Stackable HAT for Raspberry Pi -
