BACnet Field Control Device

BACnet Application Specific Controller

DSCB is a standalone BACnet B-ASC class programmable controller.


DSCB is a standalone BACnet B-ASC class programmable controller.  It is designed for monitor and control building electromechanical device, such as large AHU, pumps, fans, exhaust cabinets and other equipment. It uses 32-bit microprocessor core, communication up to 76,800 bps, transmission distance up to 1,200 meter. DSCB doesn’t have I/O point.

It must be configured EIM expansion I/O modules then it can work. Up to 4 EIM modules can be connected to it. Total number of I/O points can be selected by using different combination of EIM. In addition it has an MSnet port can connect to an external LCD control panel to make user operation and control easily at job site. DSCB conforms international BACnet MS/TP communication protocol and fully compatible with any BACnet system. It is absolutely the best product for your building.


  • Conforms to ASHRAE and ISO16484-1 defined BACnet ASC standard communication protocol, compatible with BACnet system.
  • An MS/TP(Master-Slave/Token-Passing) communication interface connect to upper layer global controller.
  • An MSnet communication interface can connect a MST20V, MST20S, DSP20U control panel or a MODBUS RTU device.
  • An EIMnet communication interface can connect up to 4 EIM I/O expansion modules.
  • User’s control program can be downloaded, edited and saved in flash memory of the controller.    
  • Carry out calculations such as proportional, integral, differential, floating, logic, arithmetic and etc.
  • 100 Binary Value(BV) and 100 Analog Value(AV) points.
  • Priority control array by 16 for all BO, AO and BV.
  • The analog value adopts high precision floating-point calculation.
  • Provide power failure backup function for all AI/BO/AO/BV/AV values keep in FRAM for at least 10 years.
  • Slide track design for space-saving and easy installation
