Waveshare Modbus RTU 8-channel Relay Module RS485
This is an industrial 8-channel relay module that is controlled by an RS485 bus and uses the Modbus RTU protocol. It has embedded protection circuits like power isolation, ADI magnetic isolation, TVS diode, and so on. It also includes an ABS enclosure.
The Modbus RTU Relay is extremely simple to use. It is an ideal choice for industrial control equipment and/or applications with high communication requirements due to its fast communication, stability, reliability, and safety. A reverse-proof circuit that prevents the circuit from accidentally being damaged by an incorrect connection. 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
What’s On Board:
Applications:
- Industrial Control - Valve control, pump station control, unattended industrial control system
- Smart Home - Controlling appliances like air conditioner, access control, purifier, water heater, and so on
- Intelligent Agriculture - Controlling door curtain motor, air blower, and so on
- Breeding And Farming - Controlling ventilator, lighting, water supply, feeding system, and so on
