It has optocoupler modules that comply with international safety standards and separate the control and load areas. It uses a high-quality single relay.\u003c\/p\u003e\n\u003cp\u003eThe inputs of this module are isolated to protect the control circuitry from any damage.\u003c\/p\u003e\n\u003cp\u003eThe power supply and relay indicators light up when the module is connected, and turn off when it is disconnected. The input signal, the signal common terminal, and the start conduction are also connected. This module can control appliances with a single-chip microcontroller and can handle both DC and AC signals. It can switch a 220V AC load.\u003c\/p\u003e\n\u003cp\u003eThis module is compatible with various microcontrollers, such as Arduino, AVR, PIC, ARM, and others.\u003c\/p\u003e\n\u003ch5\u003e\u003cspan\u003e\u003cstrong\u003eNote: \u003c\/strong\u003eOn the high level and low level-triggered mode, friends who do not understand, have a look\u003c\/span\u003e\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-level trigger refers to the signal voltage between input and trigger, can be understood as a signal input with VCC cathode short-circuit triggered a way;\u003c\/li\u003e\n\u003cli\u003eLow-level trigger refers to the signal voltage between the input terminal and Earth OV trigger, can be understood as a signal input terminal and the GND negative electrode short circuit triggered is a way  1-channel relay module connection.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 0.875rem;\"\u003e\u003cbr\u003ePackage \u003c\/strong\u003e\u003cspan style=\"font-family: -apple-system, BlinkMacSystemFont, 'San Francisco', 'Segoe UI', Roboto, 'Helvetica Neue', sans-serif; font-size: 0.875rem;\"\u003eInclude:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e1 x 1 channel 12V 30A relay control board module with an optocoupler\u003c\/p\u003e","brand":"Indian Hobby Center","offers":[{"title":"Default Title","offer_id":43059259047979,"sku":null,"price":175.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/6796\/1387\/files\/1-CH-30A-Relay-Module-2-550x550w.jpg?v=1770301345","url":"https:\/\/www.indianhobbycenter.com\/products\/12v-1-channel-30a-relay-module-with-optocoupler-isolation-12v-supports-high-and-low-triger","provider":"Indian Hobby Center","version":"1.0","type":"link"}
