Our remote I/O expansion units communicate with Modbus TCP/RTU and IEC 61850 GOOSE, allowing to extend and distribute the acquisition and command capabilities of any master device. We offer flexible I/O board configurations to fulfill any application requirement, making the iRTUe the perfect choice to both set-up and retrofit electrical communication networks.
Contemporary substation automation calls for advanced I/O modules to provide modern services such as interlocking or load shedding. These functionalities rely on state-of-the-art characteristics, which cannot be realised with serial communication media and old protocols. For this reason, the iRTUe handles IEC 61850 GOOSE messaging (with a processing time under 3ms) for newer projects but also Modbus with events buffer and timestamping for older substations/ master units.
They connect via double Ethernet (RJ45, ST or SC) or serial (EXP422) port and are synchronized with IEEE 1588 (PTP) to ensure optimal time accuracy. This allows the iRTUe to communicate with any other equipment in the network: for instance RTUs, gateways, other iRTUe modules and third-party IEDs on the substation process bus.
