Substation Automation RTU: For a good control of the electrical grid, it is mandatory to achieve a proper automation of its most critical facilities: substations. It is therefore necessary to use an open and flexible architecture for the automation system in order to allow an optimal adaptation to current and future needs. Control architecture based on iRTU telecontrol units complies with the basis of flexibility and scalability, providing a complete solution open to any technology and communication media. iRTU series products allow communicating remotely with multiple control centers while controlling all bays in a substation, using standard protocols (e.g. IEC61850, IEC60870-5-101, IEC60870-5-104, etc.) The main product in the range is the iRTU, which operates as a Remote Terminal Unit with high scalability, for both process and input/output configuration capabilities. iRTUe auxiliary units allow simple expansion with both digital and analog additional inputs and outputs. Other products, such as the iGW units, are designed to be used as communication protocol concentrators, similar to the iRTU but without the direct input/output acquisition option.

1. iRTU
Substation Automation
For a good control of the electrical grid, it is mandatory to achieve
a proper automation of its most critical facilities: Substations. It
is therefore necessary to use an open and flexible architecture for
the automation system in order to allow an optimal adaptation to
current and future needs.
Control architecture based on iRTU telecontrol units complies with
the basis of flexibility and scalability, providing a complete solution
open to any technology and communication media.
iRTU series products allow communicating remotely with multiple
control centers while controlling all bays in a substation, using
standard protocols (e.g. IEC61850, IEC60870-5-101, IEC60870-5-104,
etc.)

2. iRTU
The iRTU series is the ideal solution for Control and Automation of Substations. Due to their scalability and
modularity, these devices allows perfect adaptation for substations retrofit and upgrades.
iRTU Series products concentrate all data coming from the various facility IEDs, either through high point density
digital and analog inputs or using standard protocols (IEC60870-5-101/102/104, IEC61850, Modbus RTU, Modbus
TCP, DLMS, Procome), subsequently sending them to different control centers as defined by the electric utility.
The main product in the range is the iRTU, which operates as a Remote Terminal Unit with high scalability, both
for process and input/output configuration capabilities. iRTUe auxiliary units allow simple expansion with both
digital and analog additional inputs and outputs. Other products, such as the iGW units, are designed to be
used as communication protocol concentrators, similar to the iRTU but without direct input/output acquisition
option.
Thus, iRTU Series products may perform different functions within a facility based on their configuration: they
are able to operate as Remote Terminal Units (iRTU), as concentrators of data from other devices (iGW) or as
generic IEDs, complying at all times with the required power transmission and distribution industry standards.
Thanks to the iRTUe auxiliary equipment, iRTU devices can also be easily upgraded to more I/O, both digital and
analog.

3. iRTU
As the main RTU (or 1st level RTU), the iRTU acts as a communication gateway connecting the Substation to
the existing Control Centers through standard protocols (such as are IEC60870-5-101, IEC60870-5-104, DNP3.0,
Modbus RTU and Modbus TCP). This main iRTU can also control directly parts of the substation (auxiliary services
or bays), collect data from all devices in the substation (2nd level RTUs and IEDs), and report processed information
to Control Center/s.
Acting as an slave RTU (or 2nd level RTU) its mission is to communicate with the main RTU via an standard
protocol (e.g. IEC60870-5-101/104, DNP3.0), in order to transfer all data from the bay IEDs. Data can be acquired
either directly through its inputs, or through communication with other bay IEDs.
