| Item description |
OverviewThis 2-Channel 12V Relay Module features optocoupler isolation and supports both high- and low-level trigger signals for flexible microcontroller control. It can be used to switch AC or DC loads such as motors, lights, and other high-power devices. Designed with safety isolation, LED indicators, and a sturdy PCB, this module is perfect for Arduino, ESP32, STM32, and Raspberry Pi projects. Introductionโมดูล 2-Channel Relay 12V (บอร์ดสีแดง) ใช้รีเลย์คุณภาพสูงพร้อม Optocoupler Isolation เพื่อป้องกันสัญญาณย้อนกลับจากโหลดไฟฟ้า รองรับการเลือก High / Low Trigger ผ่านจัมเปอร์ เหมาะกับการควบคุมอุปกรณ์ไฟฟ้า เช่น หลอดไฟ มอเตอร์ พัดลม หรือโซลินอยด์วาล์ว ด้วยสัญญาณควบคุมจาก Arduino, ESP32, STM32, Raspberry Pi เป็นต้น Features
Specification
Cautionห้ามใช้งานเกินพิกัด 10A ต่อช่อง หรือต่อโหลดที่มีแรงดันสูงเกิน 250V AC / 30V DC. ตรวจสอบการเลือก High/Low Trigger ให้ตรงกับสัญญาณควบคุม. อย่าต่อขั้ว DC+ / DC− กลับด้านเพื่อป้องกันความเสียหายของออปโตคัปเปลอร์.
