Description Industrial Modbus RTU 8-ch Relay Module - RS485 Bus

This is an industrial 8 channel relay module from Waveshare. It works via RS485 bus using the Modbus RTU protocol. It features embedded protection circuitry. She has it power isolation, ADI magnetic isolation, TVS diode and more. It works with 5V, a 5V wall adapter is included as standard. On the board there are 6 relays that can switch ≤10A 250V AC or ≤10A 30V DC per channel. It is housed in an ABS housing with support for rail mounting.

Features Industrial Modbus RTU 8-ch Relay Module

  • Configurable device address (1 ~ 255), multi devices can be cascaded on RS485 bus
  • Features flash-on, flash-off function, by passing the argument to the command, it is possible to turn on the relay for a while and then close it automatically
  • Onboard unibody power supply isolation, provides stable isolated voltage, does not need additional power supply for the isolated terminal
  • Onboard unibody ADI magnetic isolation, enables signal isolation, high reliability, strong anti-interference, low power consumption
  • Onboard TVS (Transient Voltage Suppressor), effectively suppress the surge voltage and transient surge voltage in the circuit, lightning-free and anti-electrostatic
  • Onboard optocoupler isolation prevents interference from external high voltage circuit connected to the relay
  • Reverse-proof circuit, prevent the circuit from being accidentally damaged by incorrect connection
  • High quality relay, contact rating: ≤10A 250VAC/30VDC
  • Rail mounted ABS plastic housing, easy to install, safe to use
  • 3 LEDs to indicate MCU status and signal transit status
