Produktbeschreibung

  • An industrial 8-ch relay module controlled via RS485 bus, utilizing Modbus RTU protocol. It features embedded protection circuits such as power isolation, ADI magnetical isolation, resettable fuse, and TVS diode, etc. It also comes with an ABS enclosure. The Modbus RTU Relay (E) is very easy to use. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipments and or applications with high communication requirement.
  • Configurable device address (1 255), multi devices can be cascaded on RS485 bus. Features flash-on, flash-off function, by passing arguments to the command, it is possible to turn on the relay for a while and then close it automatically. 3 LEDs for indicating the MCU status and signal transceiving status
  • 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 30A 250V AC or 30A 28V DC. Rail-mounted ABS plastic enclosure, easy to install, safe to use
