This is an industrial 8-channel relay module controlled via an RS485 bus, utilizing the Modbus RTU protocol. It includes embedded protection features such as power isolation, magnetic isolation, and TVS diodes, among others. The module is housed in an ABS enclosure. The Modbus RTU Relay (B) is user-friendly and, due to its fast communication, stability, reliability, and safety, is an ideal choice for industrial control equipment and applications with high communication requirements.

Features at a glance
  • Configurable device address (1~255), multi devices can be cascaded on RS485 bus
  • Features flash-on, flash-off function, by passing 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, needs no extra power supply for the isolated terminal
  • Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
  • Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, provides over-current/over-voltage proof, lightningproof & anti-electrostatic
  • Onboard Optocoupler isolation, prevent the relay from being interfered by high-voltage circuit
  • Adopts dedicated relay driver chip, with built-in flyback diode protection, for stronger and more stable driving ability
  • Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection
  • High quality relay, contact rating up to 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
