Sedona Distributed Controllers | SDC-32Gplus Graphics Series Plus Distributed Controller, 32IOs

SDC-32G+ is a freely programmable 32-point HTML5 graphics controller using Sedona Framework™. The SDC-32G+ controllers are programmed with Sedona Workbench or NiagaraAX Workbench, or with the Open Source CPT tool. The controller are fully networkable using the Open Standards and offer both Modbus as well as BACnet communication. The controller can act as a BACnet IP or MS/TP server. The controller has can also be Modbus client over TCP/IP or over RS-485 serial connection. If the RS-485 serial connection is not used to other communications then the SDC controller can also be used as Modbus master to up to 32 Modbus slaves. The controllers can also act as a BACnet IP or MS/TP Client. Together with HTML5 graphics and SQL database provide a very effective building user interface.

The controller has 16 universal inputs, 8 digital outputs and 8 universal outputs which guarantee flexibility to a large number of the applications. The controllers support miniSD card allowing large amounts of data (historical and graphics configuration) to be stored on the device.


  • NEW more powerful 400MHz ARM processor with increased memory, offers new advanced functionality such as encrypted Email alarming and faster graphics pages.
  • Sedona Framework™ support - the industry's first open source development framework developed by Tridium, Inc. The framework allows free programmability, and a large number of applications libraries developed for SyxthSense SDC range controllers guarantee funtionality to practically any application. Furhermore, should the Sedona Framework allows further enhancements to applications as and when required.
  • Programming via Sedona Workbench or NiagaraAX Workbench allows existing programming tools to be used effectively, and the Sedona Framework™ provides graphical object programming of the controller application.
  • Programming HTML5 graphics and controller application via Online Tools inc CPT Tool.
  • SDC Controllers Supports 10/100 Base-T Ethernet Connection for Programming, HTML5 Web Interface, BACnet IP, Modbus TCP and TCOM
  • Two built-in RS 485 ports allows the controller operate as Modbus Slave or Modbus Master, and as BACnet MS/TP client.
  • Can act as a mini Modbus to BACnet gateway for up to 32 Modbus Slaves
  • High Accuracy A/D converter provides up to 12-bit resolution to analogue channels
  • Built-in 8GB microSD card interface supports data storage and graphics.
  • Controller LEDs indicate the status of inputs/outputs as well as the communication status
  • Firmware is upgradable over TCP/IP providing remote firmware upgrade path
  • Sedona Object Library Includes the most commonly used programming objects e.g. PID-loop, holiday, time schedule, logic programming, mathematical functions, email transmission, historical trend, phychometric chart, temperature vs. resistance, BACnet, Modbus and other objects
