Our remote I/O expansion units communicate with IEC 61850 GOOSE, allowing to extend and distribute the acquisition and command capabilities of IEC 61850 masters (GOOSE subscribers). 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 executes IEC 61850 GOOSE messaging in a processing time under 3ms.
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.
