 | DPC Clean Room and Laboratory Air Pressure and Volume Control System
The DPC panels which contain stand alone DPC controllers for variable volume room pressure control and constant supply volume control to maintain airchange rates. They can also be used for constant volume fresh air valve controls. All DPC panels are mass produced and pre-drilled and cut and then painted. The doors have always cut outs for the DPM pressure or volume transmitters which are tubed to the bulk head nipples located on the top of the panel. An isolator and circuit breakers for 230V are fitted as standard and all individual DPC controller circuits are fused so that in case one controller fails, the others shall carry on working. All analogue and digital in and outputs are wired to terminals and can be disconnected from the field equipment via the spade swirches built into the terminal. All DPC controllers are connected via Modbus rtu to the PLC for easy communications.

 | DPM Air Pressure - Volume - Temperature and Humidity Monitoring Panel
The DPM monitoring panel is mass manufactured and pre-drilled and cut and painted. The door houses the pressure, air volume, temperature and humidity ransmitters, converters and alarm contacts. All transmitters are wired to terminals on the back plate which can be used to connect to external LED alarm plate indicators, chart recorders 0..10V or 4..20mA or other monitoring computers. A modbus rtu communication is always standard. Additional instruments can be incorporated. All instruments can be connected to dedicated monitoring software such as WinCC Scada or others. Audit trails and compliance to FDA CFR21 Part 11 is standard.

 | PLC Clean Room and Laboratory Air Handling Central Control System
The master PLC panel is 800mm wide x 1900mm high and 400mm deep. The HMI display screen is built into the door and connected to the PLC via the profibus MPI connection. The back plate is production line manufactured and all holes and tappings are pre-drilled on a CNC machine which means the position and accuracy is always the same. The door cut outs are also pre-machined and then painted as a complete door. The cable entry point at the top is also pre-machined and a movable clamp is fitted to guide all cables into the panel. The terminal rails are always in vertical position, to allow cables to come in from the top and bottom. A shield bus bar is standard which terminates all screens to comply with EMC. There is always an isolator and cicuit breakers for the incomimng 230V single phase and each control circuit is fused. The terminals are fitted in groups i.e. if a damper motor is to be connected, all associated terminals are in one group together for easy commissioning. Each terminal has a spade switch so that the field device can be isolated without removing the wires.
