Real-Time Visibility × Effortless Configuration
Front Panel LED Indicators & DIP Switch Setup  
The IO-8AOV module is equipped with intuitive front panel LED indicators and built-in DIP switches for streamlined field operation.
The LED indicators provide real-time status feedback on power, communication, and relay output states, enabling users to verify system conditions at a glance.
DIP switches allow quick, tool-free configuration of communication parameters and node address directly on-site—simplifying setup and reducing installation time.
  • Power: Flashes to indicate the CPU is running.
  • RS485 Rx: Flashes to indicate the unit has received a valid Modbus message.
  • RS485 Tx: Flashes to indicate the unit has sent a Modbus message.
  • Dip Switch: Allows on-site configuration of address and baud rate.
  • Output Status: “ON” when the output is zero.
                              “OFF” when the output is between zero and full scale.
                              “Flashing” when the output is at full scale.
