The Numato Lab RL20001EN is a 2-channel USB relay module that offers reliability and ease of integration in a variety of automation and control applications. Thanks to built-in SPDT relays, the module allows for safe switching of circuits with a maximum current of 7A, which makes it an ideal solution for home control systems, industrial automation and DIY projects.
The module is equipped with 8 TTL (5V) compatible GPIO pins that can be used to control various devices or read the digital status of external sensors. Additionally, the module has 6 analog input channels, multiplexed with GPIO, which allows reading analog signals with 10-bit resolution.
The USB interface with CDC support allows easy integration with a computer, where the module is recognized as a serial port. Thanks to this, the user does not need to have advanced knowledge of USB to use the module, which makes it extremely easy to use.
