Waveshare Industrial Modbus RTU 8-Ch Relay Module with RS485 Bus, Multi Isolation Protection, 5V Voltage
- Industrial Modbus RTU 8-ch Relay Module, RS485 Bus, Communication interface: RS485. Communication protocol: Standard Modbus RTU protocol
- Configurable device address (1~255), multi devices can be cascaded on RS485 bus
- Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal. Onboard unibody ADI magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption.
- Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic. Onboard Optocoupler isolation, prevent the relay from being interfered by high-voltage circuit
- Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection High quality relay, contact rating: 10A 250VAC/30VDC. Rail-mounted ABS plastic enclosure, easy to install, safe to use. 3 LEDs for indicating the MCU status and signal transceiving status
