Industrial USB Modbus Relay PRO Modbus RTU Protocol USB/TTL Interface Control PLC Relay Board for Automation C

Industrial USB Modbus Relay PRO Modbus RTU Protocol USB/TTL Interface Control PLC Relay Board for Automation C Kuvaus

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 VDC, it is suitable for use with a diverse array of industrial control equipment and automation applications.
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- functionality.
Powered by a 72 MHz core and hardware timers, each relay channel can independently execute functions such as millisecond-level delayed switching (/off), periodic cycling, state toggling, and resetting. It supports simultaneous control of multiple channels without lag, ideal for production equipment interlocking and home scenarios.
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
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, CSA, and VDE certifications and meets the enhanced insulation requirements of the EN61010 standard.
