Description
The Zvezda Technology control controller is designed to collect and transmit data from meters, monitor the status of discrete low-voltage inputs, and control switching devices responsible for turning on and off the load.
The control controllers can be included in the DigiCity control cabinet or work on existing power equipment. The controller has a standalone power supply, a short response time to dispatcher commands from the web application, the ability to connect external expansion modules via RS-485, and the ability to work with SIM cards from different operators.
Applicable for:
- Data collection from an electric energy metering device and various sensors via the RS-485 interface
- Control and data collection from actuators via the DALI interface (using the RS485 to DALI converter)
- Transferring data from the controller to the dispatcher's web interface
- Prompt notification of personnel about emergencies and other events
- Work according to a pre-made schedule for 365 days, with the possibility of working without a GSM network connection (Setting
algorithms and work templates) - Visualization of the actual state and placement of controlled objects on a Web or other interface
- Automatic notification (SMS, Email, Push) of system malfunctions
- Accounting and visualization of lamp operating time and failure statistics (when using an RS485 to DALI converter)
- Visualization of electrical energy consumption by the system
- Time synchronization over the network
- The ability to work on an annual schedule or in manual mode at the dispatcher's command
- The ability to set an individual schedule for each contactor
- The ability to work with multiple counters at the same time
- The ability to fully log all controller actions in the controller itself and upload them to an ftp server
It is used to expand the signals of the DigiCity controller.
