BACnet IO Modules | BAC-DIO4 BACnet I/O Module, 2 Digital Inputs, 2 Digital Outputs

BACnet I/O Module, 2 Digital Inputs, 2 Digital Outputs

Datasheet (374kB)

BAC-DIO4 and BAC-IO9 BACnet MS/TP IO-modules have been designed for integrating remote signals to central systems. Using the BACnet MS/TP communication with BACnet I/O-modules it is easy to provide distributed architecture with often significant savings in cabling costs. The BACnet I/O-modules are wall mounted and easily used in wide range of applications.

The BACnet I/O-modules support BACnet MS/TP communication. The devices and point discovery are also supported making the device integration to the host controllers simple and easy.

BACnet Zone Input and Output Modules

Required Tools

The baud rate and address is configured through the on-board bit switch. Further configuration parameters are available over the BACnet communication.



  • BACnet MS/TP Support
  • Supports Device and Point Discovery
  • Compact BACnet IO-modules for zoning and other applications
  • 24Vac Power Supply
  • Wall mounted

Device Discovery:

The SyxthSense BACnet IO-modules support device discovery. The images below illustrate the device discovery using the CPT Tool with Sedona EasyIO FG20/FG32 and SyxthSense SDC-20G and SDC-32G controllers. The points are easily discovered and then integrated to the application logic making the network points to become integral part of the application logic.
