DSCVB5NM is a combination of controller and motorize driver certified by BTL to meet specific application BACnet Controller (B-ASC) grade programmable VAV box controller, with independent pressure sensors can be used to control a single duct VAV BOX. It uses a 32 bit microprocessor, communication speed up to 76,800 BPS.
Its MSnet communication port can be connected to the LCD screen control panel. Its EIMnet communication port can connect to 12 EIM I/O expansion modules.
DSCVB5NM provides a full range of options for precise control of the variable air volume box. It is definitely the best equipment for your monitoring system.
【Features】
- In accordance with the ASHRAE BACnet protocol. Compliance with the standard BTL B-ASC class specifications.
- MS/TP (Master-Slave/Token-Passing) communication interface. Communication speeds up to 76,800 BPS and transmission distance up to 1,200 meters.
- The MSnet communication interface can connect MST32V display panel.
- NTC temperature sensor port can connect 10KΩ NTC temperature sensor.
- High accuracy air pressure differential sensor, same in either direction, low air flow, fully IC packed to prevent dust influence.
- Damper motor using actual position feedback signal, more accurate than the floating control.
- Support online editor, download control logic program, real-time program debugging and firmware update function.
- With enthalpy, dew point temperature, PID control and all common program functions such as logarithms, trigonometric functions, roots and other advanced math function.
- 100 BV and 100 AV points.
- Standard floating point operation for analog point. Its large value range saves additional work for ratio multiplication.
- Provide power failure backup functions for all AI/BO/BV/AV values keep in FRAM for at least 10 years.
- Priority control array by 16 for all AO and BV.
