EV RE-01-0808 (WiRIO3 I/O Extension Unit)

FW-Bus Client

  • Connect with FW-Bus Host.
  • Can support up to 8 units of the device
  • DIP Switch to select the Device ID.

Internal power supply with DC/DC converter to reduce power wastage

  • Input DC 12V to 24V.
  • Reverse polarity protection.

Onboard Input and Output Port

  • 8 input ports and 8 output ports.
  • Able to configure the input port as I/O input or user push-button input.
  • Push button input can detect single press, double press, triple press, and long press (press and hold more than 4 seconds).
  • Provide a number of input on/off cycle counter to prevent missing cycle.
  • Wet contact output design using MOSFET thus support up to 30V 1A output current without the wear and tear of the relay contact.
  • The output port can be configured as standard High/Low output or Pulsed output.
  • Configurable pulse duration (configure separately for High level and Low-level periods) and a number of pulse cycles when triggered by the server.
