Waveshare Waveshare Modbus RTU 8-Channel RS485 Relay Module With Digital Input Multi Isolation Protection Circuits, 7~36V Power Supply
1. This product is an industrial-grade 8-channel relay module controlled by RS485 interface, featuring 8-channel switch input, adopting Modbus RTU protocol, and equipped with built-in power isolation, magnetic coupling isolation, and TVS protection circuits. It is designed with an ABS housing. This product is easy to operate and features fast communication speed, stability, reliability, and safety. It is suitable for various industrial control devices or applications with high communication requirements.2. It supports setting the device address (1 to 255) to cascade multiple devices through the RS485 bus.3. It has flashing on and off functions, allowing parameters to be set in the instructions to operate the relay to turn on for a certain period and then automatically turn off.4. It has an integrated power isolation circuit on the board, providing stable isolated voltage, and the isolation end does not require additional power supply.5. It has an integrated magnetic coupling isolation circuit on the board, capable of signal isolation, with high reliability, strong anti-interference, and low power consumption.6. It has a self-resetting fuse and TVS (transient voltage suppressor) on the board, effectively suppressing surge voltage and transient peak voltage in the circuit, preventing overcurrent and overvoltage, and protecting against lightning and static electricity.7. It has an integrated optocoupler isolation circuit on the board to prevent interference from the relays high-voltage circuit.8. It uses a dedicated relay driver chip with built-in freewheeling diode protection, providing stronger and more stable driving capability.9. The switch input has bidirectional optocoupler isolation, supporting both passive and active switch input, with an internal anti-bounce algorithm. The relay supports switch input linkage mode or flip mode control.10. It has an anti-reverse connection circuit on the board to prevent damage to the circuit from reversed positive and negative connections.11. It uses high-quality relays, allowing a load of up to 10A 250V AC or 10A 30V DC.12. It has a rail-mounted ABS protective housing, making installation and use convenient, and is safer with the housing.13. It has an external LED indicator light for easily checking the MCU status and signal transmission and reception status. Parameters:1. Power Supply Voltage: 7 - 36V2. Communication Interface: RS4853.
