ELEGOO Relay Module 4 Channel DC 5V with Optocoupler for Arduino UNO R3 MEGA Project 1280 DSP ARM PIC AVR STM32 Raspberry Pi

About this item

5V Active Low Operation: This relay module operates at 5V and should not be powered by 3.3V, as it may not drive the relays effectively. Ensure the power supply current exceeds 1A for reliable performance. | High Current Handling: Each relay can handle maximum contact ratings of AC250V 10A and DC30V 10A, making it suitable for controlling various appliances and devices requiring high current. Working status indicator lights are conducive for the safety use | Standard Microcontroller Interface: Features a standard interface for direct connections with microcontrollers such as Arduino IDE, Raspberry Pi, STM32, AVR, PIC, and ARM, allowing for easy integration into projects. | GPIO Low-Level Logic Control: This 4-channel relay module utilizes low-level logic voltage to drive the relays, which reduces power consumption and protects the control board from damage. This allows ESP32 and Raspberry Pi GPIOs to directly control the relays without the need for external transistors or logic-level converters. | Applications: Widely used for all MCU control, industrial sector, PLC control, smart home control.
