PCD46440 Programmable ControllerDetailed product description：

Overview
The PCD46440 programmable controller is suitable for automatic control of building equipment, factory equipment, environmental equipment, automatic water supply and drainage equipment, etc. It can automatically adjust the operating status of various central air conditioning, chiller, water pump, dosing pump, solenoid valve, frequency converter and other systems according to various user requirements and under different external environmental conditions, to meet the monitoring and control of pressure, flow rate, temperature, water quality. This control can also be used for power monitoring, water supply and drainage control, and refrigeration station monitoring. Depending on the control object, various methods such as decentralized DDC control and distributed DDC control can be selected, making it flexible and reliable in operation.
Functions and features
1. Real time on-site measurement of switch signals and analog signals, displaying the measured values of the measured parameters on site in real time.
2. Real time modification of set values and control parameter values.
3. Fully automatic operation control.
4. Data power failure protection function.
5. Manual and automatic switching function.
6. Fieldbus CAN BUS communication function, RS-485 communication function.
7. Password protection: mainly to protect the settings within the system, so as to ensure that only authorized personnel can access and update
Data within the new system.
8. Timing control: The controller can be started and stopped according to the schedule set by the operator.
9. Small size: This product adopts a compact structure, so its installation is very free.
10. I./O module configuration: Depending on the required functionality, the input and output types can be selected, and the actual number of managed points can be increased or decreased.
11. Programmable: Strong programmability, able to directly program complex applications in C language.
12. It can be connected to the user interface module, so setting change operations can be implemented on the controller site.
13. Implement remote control through user terminals
Remote device operation/stop control and temperature setting change operations can be achieved by connecting to the user terminal.
14. Connection with the central monitoring system: By connecting to the central monitoring system through the CAN communication protocol, building equipment can be centrally managed.
15. Self discipline and decentralization: Even in the event of abnormalities in the central monitoring system, this product can independently perform backup operations, thus dispersing the risk of system failures.
16. Installation: DIN rail installation or screw installation can be selected.
17. High reliability, strong anti-interference ability, and overvoltage protection function.
18. Easy to operate.
