A BMS consists of…show more content…
2.0 SENSOR AND ACTUATORS USED ✓ Temperature Transducers [pic] [pic] ✓ Pressure sensors [pic] [pic] ✓ Humidity Sensor ✓ Differential Pressure sensors [pic] [pic] [pic] [pic] ✓ Humidity Transducers [pic] [pic] [pic] [pic] ✓ Level sensors ✓ CO2 sensor ✓ Flow Meter ✓ CCTV Cameras ✓ Light sensors ✓ Occupancy sensors ✓ Water Pumps ✓ Valve actuators ✓ Fans 3.0 DETAILS OF CONTROLLERS/DDC USED Inputs allow the controller to read temperatures, humidity, pressure, air flow, and other essential factors. The outputs allow the controller to send command and control signals to slave devices, and to other parts of the system. Inputs and outputs are digital or analog. The BMS is facilitated with a System/Network controller as this is a Supermarket/Office building. System controllers provide general purpose feedback loops, as well as digital circuits. System/Network controllers are applied to control more mechanical systems such as an Air Handler Unit (AHU), boiler, chiller, etc. Terminal Unit controller is used for control of lighting. |POINT SCHEDULE -BUILDING AUTOMATION SYSTEM (TRELLEBORG LANKA (PVT) LTD | | | | | |
