Data on the equipment’s condition is transmitted on a 24-hour basis to the control centre, where a manager monitors the equipment’s condition and takes timely actions in case of malfunctions.

The system significantly reduces maintenance, replacements and staff costs.

 Equipment set

 Unilight controller

Data on the condition of a substation’s components is transmitted through wireless channels: GSM, LORA. Can be easily connected to the existing substations. Technical characteristics:

  • 27 discrete inputs
  • Two RS-485 interfaces
  • Built-in GSM modem, 3G support, dual-SIM
  • Remote software updates
  • Remote relay control

 Additional discrete input/output modules

The modules’ purpose is to increase the number of channels for sending and receiving data, as well as control signals being transmitted to RS-485 network.

The modules increase the number of discrete inputs and outputs managed by one Unilight logic controller and this easily scale the substation monitoring system.
