Function and Smart Boards

Function Boards

Function boards are small plug-in circuits that use an I/O channel in it’s native I/O mode. The function board may use one or more signal lines (digital in, digital out, analog in). The module has no way of knowing which function board is plugged in and the usually the matching widget need to be tailored to suit the function. For example, when a Temperature Probe function board is attached, a user will need to set the Scaling for that channel’s analog input to Temp F or Temp C. This will convert the normal raw value, 0 to 1023, into a temperature that can be displayed.

  • Channel Tester (FB-1) – used to test all the I/O channel signal lines
  • Temperature Probe (FB-2) – measures temperature
  • DPDT Relay Board (FB-3) – actuates a relay from the digital output
  • Ambient Light Sensor (FB-4) – measures light
  • Terminal Board (FB-5) – provides screw-terminal style attachment points
  • Buzzer Board (FB-6) – emits a 2kHz tone at 85dB
  • Serial LCD (FB-7) – display messages using any serial connection
  • Humidity Sensor (FB-8) – Measure 0% to 100% relative humidity

    Smart Boards

    An ioBridge Smart Board extends the functionality of the IO-204 module and provides more complex functionality than function boards. Please note that Smart Boards are NOT compatible with the IO-204-PRO.

    The following Smart Boards are currently available:

  • Servo Controller Smart Board (SB-1)
  • X10 Smart Board (SB-4)
  • Serial Smart Board (SB-5)

  • Please visit our online store to purchase ioBridge Smart Boards.
