The Waveshare Industrial Modbus RTU 8-Ch Relay Module w/ RS485 Interface, 5V Power Supply is an advanced industrial relay module designed for efficient control via the RS485 bus using the Modbus RTU protocol. It is equipped with embedded protection circuits, including power and magnetic isolation, as well as a TVS diode, ensuring robust performance and safety. The module is housed in a durable ABS enclosure, making it suitable for various industrial applications requiring high communication standards.

This relay module supports configurable device addresses, allowing multiple devices to be cascaded on the RS485 bus. It features a flash-on, flash-off function, enabling the relay to be activated for a specified duration before automatically turning off. The onboard unibody power supply and magnetic isolation provide stable voltage and signal isolation, enhancing reliability and reducing power consumption. Additional safety features include a resettable fuse, TVS for surge and transient voltage protection, optocoupler isolation to prevent interference from high-voltage circuits, and a reverse-proof circuit to safeguard against incorrect connections.

The module is designed for easy installation with a rail-mounted ABS plastic enclosure and includes three LEDs to indicate MCU status and signal transceiving status. It is an ideal choice for industrial control equipment, offering fast communication, stability, and reliability.
