Product description
- 5 V Active Low Operation: This relay module operates at 5 V and should not be powered by 3.3 V, as it may not drive the relays effectively.
- Ensure the power supply current exceeds 1 A for reliable performance.
- High Current Handling: Each relay can handle maximum contact ratings of AC 250 V 10 A and DC 30 V 10 A, making it suitable for controlling various appliances and devices requiring high current.
- Working status indicator lights are conducive for the safety use.
- Standard Interface: Features a standard interface for direct connections with microcontrollers — compatible with Arduino, 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, the industrial sector, PLC control, and smart home control.
