Modular design project ARIS C303 bay controller is designed for a single bay or multiple bays equipment monitoring and control. It provides direct data input of signals from current and voltage transformers, of binary input signals, of normalized analog signals as well as output of binary and control signals. Bay controller is used in substation process control systems, data acquisition and transmission systems, technological data acquisition and transmission systems, etc.

Key Functions:

  • Measurement and calculation of more than 80 secondary electrical parameters of three-phase four-wire network
  • Display of electrical network parameters and power quality parameters at bay controller display
  • Reception of up to four IEC 61850-9-2LE streams (80 samples/cycle or 256 samples/cycle)
  • Data exchange with other devices using digital communication protocols
  • Electrical parameters calculation according to EN 50160:2010 standard
  • Input of standard current and voltage analog signals
  • Execution of user-defined algorithms, interlocking algorithms
  • Output of binary and control signals (24 VDC or 220 VDC/VAC)
  • Input of binary signals (24 VDC or 220 VDC/VAC)
  • Processing of double position signals
  • Electrical energy technical metering
  • Assignment of timestamps with an accuracy of 1 ms
  • Data archiving (analog and binary signals)
  • Event log administration and display
  • Operation as NTP-server
  • Display of mimic diagrams at bay controller display
  • Fault recording COMTRADE format
  • Recource calculation of the fault iterrupter switch
