DSCV350B

BACnet Field Control Device

BACnet Application Specific VAV Controller

DSCV350B is a standalone BACnet B-ASC class programmable VAV controller. It has a high accuracy air pressure differential sensor for single pipe VAV box control.

Description

DSCV350B is a standalone BACnet B-ASC class programmable VAV controller. It has a high accuracy air pressure differential sensor for single pipe VAV box control. Its calibrate function in BACsoft is an advantage of adjustment accuracy at site when air flow is stable. This function helps user to remove the inaccuracy caused by installation process.

DSBV350B provides high accuracy VAV control by combine this air pressure sensor and the calibrate function in BACsoft. DSCV350B conforms international BACnet MS/TP communication protocol and fully compatible with any BACnet system. Communication speed 76,800 bps. It works standalone by using a MST20 LCD control panel. Universal inputs of DSCV350B can monitor binary and analog input signals.

Features

  • Conforms to ASHRAE and ISO16484-1 defined BACnet AAC standard communication protocol, compatible with BACnet system.
  • An MS/TP(Master-Slave/Token-Passing) communication interface connect to upper layer global controller.
  • A MSnet communication interface can connect a MST20V, MST20S, DSP20U control panel or a MODBUS RTU device.
  • High accuracy air pressure differential sensor, same on either direction, low air flow, fully IC packed to prevent dust influence.
  • Calibrate function in BACsoft for advantage of adjustment at site when air flow is stable.
  • User’s control program can be downloaded, edited and saved in flash memory of the controller.    
  • Real-time debug function, save programming time.
  • Carry out calculations such as proportional, integral, differential, floating, logic, arithmetic and etc.
  • 100 BV and 100 AV points.
  • Standard floating point operation for analog point.  Its large value range save additional work for ratio multiplication.
  • Provide power failure backup function for all AI/BO/AO/BV/AV values keep in FRAM for at least 10 years.
  • Priority control array by 16 for all BO, AO and BV.
  • Slide track design for space-saving and easy installation.
  • Plug-in terminal blocks and LED Indicators of communication and status are convenient for system debug.
