Description

Waveshare Industrial Modbus RTU 8 Channel Relay Module RS485 This is an industrial 8-channel modbus relay module that is controlled by an RS485 bus and uses the Modbus RTU protocol. This 8 channel RS485 relay module features embedded protection circuits like power isolation, ADI magnetic isolation, TVS diode protection, and more, ensuring reliable performance in demanding environments.

It also includes a durable ABS enclosure for added safety. The Modbus RTU relay is extremely simple to use. This modbus relay is an ideal choice for industrial control equipment and applications with high communication requirements due to its fast communication, stability, reliability, and safety. A reverse-proof circuit prevents the module from being damaged by incorrect wiring.

The MCU status and signal transceiving status are indicated by 3 LEDs, they are: LED indicators used: STA: MCU indicator, keep flashing when the MCU normally working TXD: TX indicator, light up when sending data RXD: RX indicator, light up when receiving data Also, read our blog on Applications of Relay explaining 8 major applications, what is it, how does it works, its construction, and different types of relays.

Modbus Relay Module Applications: This waveshare relay module is widely used in industrial automation, smart control systems, IoT-based monitoring, and remote device switching. As a Botroniqst RS485 relay module, it enables long-distance communication with multiple devices over a single bus, making it suitable for scalable automation setups.

Whether you're building PLC-based systems or integrating with microcontrollers like Raspberry Pi or Arduino, this modbus relay module ensures efficient and reliable switching control. Features Configurable device address (1~255) allows multiple devices to cascade on the RS485 bus. Flash-on, flash-off function enables automatic relay shutdown after a set time.

Built-in isolated power supply ensures stable voltage without extra power. ADI magnetic isolation for high reliability, strong anti-interference, and low power consumption. TVS protection suppresses surge and transient spike voltage for lightning-proof and anti-static safety. Optocoupler isolation prevents interference from high-voltage circuits. Reverse-proof circuit protects against damage from incorrect wiring.

10A 250VAC/30VDC contact rating. Rail-mounted ABS plastic enclosure for easy installation and safety. Three LED indicators display MCU and signal transmission status.
