ISIO 200 is a simple and versatile binary I/O terminal with IEC 61850 interface. For communicating with CMC test sets and real-time message exchange with peer devices, the fast GOOSE messaging is used.
By using Client/Server communication, ISIO 200 can be integrated into Substation Automation Systems (SAS) and communicate to a station controller.
In combination with a CMC test set, ISIO 200 extends the binary I/O capability of the test system. As a component of an SAS, it handles additional binary signals. Due to its compact design, binary I/O terminals can be put wherever necessary.
Test setups in SAS often require bridging of long distances or an extension of the CMC’s binary I/O capabilities. The ISIO 200 can be used as accessory for the CMC to increase the number of binary I/Os of the test system. The accessory can be confi gured easily using the Test Universe ISIO Connect module.1 The CMC and ISIO 200 communicate via GOOSE messages. This allows distances to be bridged up to dozens of meters with an Ethernet cable.
Testing sophisticated protection schemes
When testing protection schemes with main and backup protection and telecommunication, the setup can easily get so complex that more than 10 binary inputs and 4 binary outputs are required. In such cases, the ISIO 200 is the ideal extension of the CMC’s binary I/O capabilities.
Access to remote binary I/O terminals
Connecting to binary I/Os that are more than just a few meters away from the test set is often cumbersome. The ISIO 200 can be conveniently placed close to remote access points to keep the conventional wiring as short as possible. The longer distance to the test set is simply bridged with an Ethernet cable.
Permanently installed test terminal
The binary I/Os of a protection relay are permanently wired to an ISIO 200. For testing, the binary wiring of the test set is reduced to connecting the Ethernet cable. The ISIO 200 becomes powered as soon as it is connected to the CMC.
