Connecting 3.3V or 5V logic microcontrollers (like Arduino, ESP32, or Raspberry Pi) directly to high-voltage components carries a risk. Motor noise, voltage spikes, and electromagnetic interference (EMI) can crash your processor or permanently damage your board.\u003c\/p\u003e\n\u003cp data-path-to-node=\"9\"\u003e \u003c\/p\u003e\n\u003cp data-path-to-node=\"10\"\u003eThe \u003cb data-path-to-node=\"10\" data-index-in-node=\"4\"\u003eTLP281 4-Channel Opto-isolator Module\u003c\/b\u003e is your safety net. It uses light signals—rather than direct electrical connections—to transfer data between two isolated circuits. This effectively \"air-gaps\" your sensitive processor from the noisy, high-voltage side (up to 24V).\u003c\/p\u003e\n\u003cp data-path-to-node=\"10\"\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"11\"\u003e\u003cb data-path-to-node=\"11\" data-index-in-node=\"0\"\u003eLogic Correction Built-In\u003c\/b\u003e\u003c\/h3\u003e\n\u003cp data-path-to-node=\"11\"\u003eStandard opto-isolators often invert your signal (High becomes Low), forcing you to rewrite your code.
