iRTU – The Best Controller for Your SCADAWhy use a common PLC, when you can have a modular RTU made for substation environments?
Our secure and scalable RTUs can simultaneously handle older (e.g. Modbus) and newer (e.g. IEC 61850) protocols on serial, wireless and Ethernet networks — making substation automation less complex and more affordable.
Remote telecontrol units (RTUs) for SCADAs are frequently employed as bay controllers for data acquisition in substations, often requiring further devices for gateway and more advanced functionalities like load shedding or microsecond timestamping. Our modular iRTUs are powerful controllers with embedded ethernet switches, state-of-the-art features and internal I/Os, allowing you to do it all with one small device.
They can map serial servers to IEC 61850 logical nodes, collect and process data from old and new IEDs, report directly to the cotrol center with any standard protocol (e.g. IEC 60970–5‑104, DNP3) and handle all common protocol conversions: Modbus to IEC 61850, IEC 101 to IEC 104, Modbus RTU to Modbus TCP, Modbus to Ethernet IP (Serial to Ethernet in general), IEC 103 to DNP3 and many more.
A network architecture based on iRTUs is open and scalable: you can easily integrate future generations of devices (IEDs, sensors, routers etc.) and adapt to any present and future needs, such as changing the network topology or communication media.

- Full range of protocols (DNP3.0, IEC 61850, IEC 60870–5… ) to communicate with all devices and control centers connected to your electrical network.
- Embedded Ethernet switch with (2) 10/100 BaseTx, (2) FX100 fiber optics and RSTP/ PRP/ HSR redundancy
- Up to 4 Ethernet ports, 4 serial ports, and optional, internal 4G, 3G and GPRS modems
iRTU as Bay Control Unit
The iGW comes with 2 independent 10/100 BaseTX Ethernet ports (two different MAC addresses, RJ45 connector) and an internal Ethernet switch with (2) 10/100BaseTX, (2) fiber optic FX100 sensors with ST, SC o SFP connectors, and RSTP /PRP /HSR redundancy.
Additionally, the iGW carries 4 software configurable serial ports: 1 full RS-232/RS-485/RS-422 + 2 basic RS-232/RS-485/RS-422 and 1 RS-422/RS-485 port (EXP422) to connect iRTUe models. Optionally, one of the serial ports can be replaced with an internal 4G(LTE), 3G and GPRS modem.
The iRTU manages a broad range of time synchronization methods with fault tolerant priority schemes (NTP, IEEE1588/ PTP, IEC60870‑5–101, DNP 3.0) to ensure that your network is synchronized and you can retrace any network failures.
The time stamp accuracy of the iRTU is superior to one 1ms and has a 1 microsecond resolution. In case the time server fails, the iRTU can rely on its high accuracy real time clock (1.5ppm) as a backup.
IEC61131‑3 PLC Automation
Thanks to its internal PLC based on IEC 61131–3, the iRTU can provide powerful automation and control functionalities.
For example, you can easily reuse programs on different projects, run multiple PLC instances simultaneously or use triggered variables for control commands and set points. It also allows to run hot program updates, stop PLC executions depending on the quality of selected PLC inputs and debug PLCs online, either cycle-by-cycle or step-by-step.
The iRTU has a high execution speed – a 2000 ST line program takes less than 3ms.
Standards and Compliance
The diverse backgrounds of our partners and clients from all over the world have helped us gather state-of-the-art know-how and firsthand experience in a great variety of energy applications. This joined knowledge is the foundation of our optimized iRTU/GW family, which has a proven track record of being particularly effective and resistant for a diverse range of applications and harsh environments belonging to the energy industry.
As a result, the iRTU meets the requirements of extensive standards, such as IEC61850‑3, IEC60870‑2–1 & IEC60255-26.
Protocols & IP Networking
The iRTU was designed to use a high number of protocols (see data sheet) and communicate with several control centers at once. It is equipped with transparent TCP bridging and configurable IP routing to tunnel any serial protocol (such as Modbus) over a TCP/IP connection and facilitate the control of complex IP networks.
The iRTU IEC 61850 capabilities have been A level certified by DNV-KEMA.
Inputs and Outputs
iRTUs are equipped with internal I/O modules for direct data acquisition and feature a 2.5kV isolation. The DIs can be chosen in 4 voltage levels (or customized) and grant a 1 ms timestamp accuracy. Each input can also be defined as a counter and provide individually configurable debounce and decluttering filters. Its AIs have a current range of ±20 mA (other voltages and currents upon request) and a 0.15% accuracy.
The iRTU also offers internal dry contact electromechanical relay outputs in several ratings and with an isolation of 6 kV.

In this project, the iRTU-B0C1 reads the metering data from metering IEDs (transferred through an RS485 bus) via Modbus RTU and passes the data to a local utility as well as to a local operator, who is in charge for the MV section.
In this project, the iRTU is used to remotely control and supervise over 100 photovoltaic generation plants around Turkey. At each PV plant, one iRTU gathers the data with a 1ms time accuracy from dozens of inverters (via ModbusRTU), meters (via IEC 62056–23), and protections relays (via IEC 61850) and transfers the data via IEC60870‑5–104 through GPRS (secured VPN connection) to the control center, where it’s stored on an SQL database.
In this project, the iRTUs control meters and protection relays from different manufacturers (ABB and Siemens) using communication protocols like Modbus and DNP3.0. The data collected from the IEDs (meters and protection relays) is sent to the control centers via DNP3.0.
iGWs and iRTUs can be freely extended by connecting several iRTUe.
They are IEC 61850 (GOOSE) compliant and come in many configurations such as 48 DI, 16 relays, 16 AI, 24 DI + 8 relays, 24 DI + 8 AI or 8 relays + 8 AI.
High-performance SCADA for the visualization and control of substation data. It is able to run either in client/server or standalone modes, providing advanced functionalities such as hot-standby redundancy, automatic line coloring, events notification (via e‑mail and sms), SQL logging, and reports generation.
