​KEAcvise 4-Pack 5V 1-Channel Relay Module - Optocoupler Isolated High/Low Level Trigger Switch for Arduino/Home Automation/Industrial Control/IoT Devices (4-Pack)​

• Control Equipment The single-channel relay module employs a high-quality DC5V relay and SMD optical isolator, supporting high/low level triggering and widely used for controlling various AC/DC and high-current devices.
• Load Range For the normally open state, the maximum load is < AC 250V/10A and < DC 30V/10A. The trigger current of the optical isolator is 5mA.
• Fault-Tolerant Design The relay will not operate even if the control line is disconnected, ensuring safety and stability.
• Universal Interface Equipped with screw terminal blocks and fixing bolt holes (diameter: 3.1 mm) on both sides for easy installation.
• High Compatibility The relay module can be directly controlled by 5V logic signals from microcontrollers such as 8051, AVR, PIC, DSP, ARM, Raspberry Pi, MSP430, and TTL logic.
