The Pressure Control Unit creates a sterile environment by keeping the ambient pressure high.
The system consists of three main components. The first unit controls a room. It has a pressure reading sensitivity of 10 bits. It has 2 digital and 2 analog input-output channels. With the 2x8 character LCD on it, it can instantly display the ambient pressure.
The second unit controls 2 rooms at the same time. It has 24-bit pressure reading sensitivity. It has 7 analog + 5 digital inputs, 3 analog + 2 digital output channels. It can direct the output channels with the PID algorithm. It is a professional product with 128 x 64 graphic LCD.
The third unit is the central control unit, which establishes a network with the other two units over the internal BACnet ports, displays the parameters on the other two systems and notifies the alarm conditions. It has a voice notification system. Each unit can control up to 24 rooms.
As the common features of these three units, external LonWorks and BACnet modules can be installed on them. It is compatible with the building automation system.
