It employs the standard Modbus RTU protocol-a universal industrial standard-eliminating the need for custom protocol development and enabling immediate, out-of-the-box operation. Featuring dual communication interfaces with clearly defined pin assignments, the module offers true plug-and-play functionality. Dual Local/Remote Control Capability: Local Control-Direct connection via UART/USB ensures rapid response with zero latency. Remote Control-When paired with 4G or Wi-Fi modules, the device can integrate with IoT platforms to enable cloud-based control, making it highly adaptable for various IoT applications and compatible with a wide range of loads This product is a dual-interface control relay module (USB/Serial) designed specifically for industrial environments. Utilizing the Modbus RTU protocol and supporting a wide input voltage range of 8-36 , it is suitable for use with a diverse array of industrial control equipment and automation applications. Powered by a 72 MHz core and hardware , each relay channel can independently execute functions such as millisecond-level delayed switching (on/off), periodic cycling, state toggling, and resetting. It supports simultaneous control of multiple channels without , ideal for production line equipment interlocking and smart home scenarios. Equipped with industrial-grade relays, the module offers exceptional durability and an ultra-long operational lifespan, supporting the switching of medium-power loads ranging from lighting systems to small electric motors. It holds UL, , and VDE certifications and meets the enhanced insulation requirements of the EN61010 standard., Weight: 0.3086471668 Pounds, Manufacturer: Wesafrae
