1 channel relay module 2-way relay expansion board 5V

Description

The 1-channel 5V control SPDT High-level trigger AC power relay board offers seamless integration with microcontrollers, facilitating precise control and manipulation of electrical systems up to 10A at 250V AC. Notably, its isolated inputs safeguard sensitive control circuitry from potential damage or interference, ensuring dependable operation even in environments prone to electrical noise. Operating in low-level trigger mode with a pull-down circuit mechanism, coupled with a triode drive and high-impedance controller pin, enhances the reliability and stability of the relay board’s performance. Compliant with international safety standards, this relay board provides users with confidence in its reliability and safety, featuring indicators for power supply, control, and relay output status for clear operational feedback.

Despite its robust functionality, the relay board maintains a compact form factor measuring just 3.8 x 2.6 x 1.8 cm, making it highly versatile for integration into microcontroller development board modules or for controlling various home appliances with ease. Adhering to the specified contact rating ensures optimal performance and longevity, with the board operating within a wide temperature range (-40 to 85°C) and capable of switching both AC and DC voltages (250V AC and 30V DC respectively). With a trigger current of 20 mA and a trigger voltage of 5V DC, it provides efficient and responsive control over connected devices or systems, promising versatility and reliability across diverse operating environments.
