RTU7MC3 (RTU7MC3-D) – Communication Unit

Unit Description

The RTU7MC3-D is advanced universal communication unit, based on embedded computer with Linux core. The HW core is extended by ELVAC SW based on long time experience in power distribution field and protocols used in this area.

These all features offer to the user of this device very powerful tool for protocol conversion and communication between devices and SCADA system.

The device supports complete remote management, FW and OS updates.

Typical Applications

  • main communication unit in substations and other energetics objects,
  • communication protocol converter in electrical energy sector,
  • redundant (backup) communicator with SCADA,
  • data concentrator,
  • router.
