Description
Modbus RTU Relay (B) is an industrial relay module controlled via RS485 interface, supporting the standard Modbus RTU protocol. Thanks to advanced protection circuitry such as galvanic isolation of power and signal lines, TVS diodes, and optoisolation, the module ensures a high level of safety, stability, and reliability. It is designed for industrial applications requiring fast and fault-resistant communication.
The module features 8 relays with a maximum switching current of 10A at 250VAC or 30VDC, allowing for direct control of both household and industrial devices. The ABS enclosure is suitable for DIN rail mounting, making integration into existing installations easy. The device supports RS485 address configuration in the range of 1–255, enabling multiple modules to be connected on a single bus.
Additional features such as flash-on/flash-off (timed relay activation) and built-in LED indicators for operation status significantly improve diagnostics and usability. The wide input voltage range of 7 to 36V makes the module highly versatile and ready for use in various environments. The system is based on dedicated control chips to ensure reliable relay operation and resistance to interference. It is an excellent solution for applications such as building automation, device control, monitoring, and industrial system integration.
