IRZ-502 large-scale technological production variable frequency drive


Ensuring of continuous high-flow technological process requiring a fault-tolerant control system.

The product provides the following:

  • automatic control and fixation of the values of the main technological parameters of monitored objects (pressure, level, temperature, etc.)
  • providing operators with remote control of the operation of technological equipment (pumps, electric valves, valves, etc.)
  • prevention of emergencies and protection against erroneous actions of personnel
  • maintaining archives of data on the progress of processes, changes in parameters, events and personnel actions
  • diagnostics of a complex of technical means

Monitored parameters

  • level, pressure, vibration, temperature, etc.
  • flow rate, water cut and oil quality
  • any technological parameters according to the customer's requirement


  • application of controllers with real-time operating system
  • connection of the upper level to non-standard equipment
  • hot redundancy of main controller
  • redundancy of the cabinet main units
  • communication with remote objects through the "optical ring"
  • display of the operation main parameters on the built-in graphic panel
  • uninterruptible power of the system is ≥1 hour
  • availability of automatic through-over circuit breaker (ATC) on power supply
  • hardware separation of the distributed control system and the emergency protection system
  • use of elements for cabinet structure with SIL2 and SIL3 certification according to IEC 61508 for highly hazardous industries
  • cabinets are delivered with application software and their commissioning is performed at the customer's site
