Field Control Layer Device

VAC Controller with Actuator (B-ASC)

DSCV ... B is a BACnet (B-ASC) grade BTL approved programmable VAV box controller combined with a powerful 10nm actuator and independent pressure sensor that can be used to control a single duct VAV BOX.

Description

DSCV ... B is a BACnet (B-ASC) grade BTL approved programmable VAV box controller combined with a powerful 10nm actuator and independent pressure sensor that can be used to control a single duct VAV BOX. It uses 32 bits microprocessor, communication speed up to 76,800bps and Lan network distance up to 1,200 meters. There are 2 Universal inputs that
accept digital or analog input signals, 3 digital output points and 2 Analog outputs (model specific). It is possible to connect a remote LCD or Color Touch screen or configure the MSnet port as a Master/Slave Modbus port for communication with other non BACnet devices for remote monitoring and or control. The controller is simple and quick to install and comes pre-programmed but can be reprogrammed to meet specific application
making this device a powerful and flexible low investment product.

Features

  • BACnet Application Specific Controller (B-ASC) class listed device.
  • MS/TP (Master-Slave/Token-Passing) communication interface that connects to the upper layer, global controller.
  • MSnet communication interface can connect a MST…, DSP…, DST… control panel or a MODBUS RTU master or slave device.
  • High accuracy air pressure differential sensor for low air flow accuracy, fully IC packed to prevent dust ingress.
  • BACnet Calibration points for accurate air flow readings.
  • Using Airtek Bacsoft software the user can download, modify site specific programs and saved to the flash memory in the controller.
  • Real-time debugging function, saves programming time.
  • Can perform calculations such as proportional, integral, differential, floating, logic, arithmetic and etc.
  • Onboard 100 BV and 100 AV points.
  • Standard floating point operation for analog point. (Large value range saves additional work for ratio multiplication).
  • Power failure backup function for all AI/BO/AO/BV/AV (values kept in FRAM for at least 10 years).
  • 16 Priority array for all BO, AO and BV.
  • Combined Controller and actuator for fast and easy installation, built in clutch for manual adjustment, travel limiting stoppers..
