Pressure Control Unit ...

The Pressure Control Unit keeps the sterialized room as it is via controlling the inside and outside pressures.

The system has three units. First unit controls one room and has 10 bits pressure precision sensitivity. It has 2 analog and 2 digital I/O channels,and a 2 x 8 character LCD to show the pressure level.

Second unit controls two rooms simultaneously also has 24 bits pressure precision. In total, there are 17 I/O channels. These are 7 analog + 5 digital input, and 3 analog + 2 digital output channels. This unit can conduct to output channels with PID algorithms. It has a 128x64 graphic LCD.

Third unit is a central control module which controls the other units up to 24 rooms and communicates with the other units via BACnet ports. It shows other units’s parameters and informs alarm status. There is a voice instruct..

The three units can communicate via LonWorks and BACnet .
They are compatible with building automation systems.
