The maximum number of SAU900 control by the RTU (all the rack) is equal to 8 modules (32 serial links). Each rack can support many protocol in same time on the same SAU900. To connect IEDs in Modbus it is necessary to add an external converter RS232/RS485. To connect IEDs in K-Bus Courier it is necessary to add an external KITZ101 or 201.

RTU S900 CAPACITY Up to 256 devices (numerical protections or IEDs)
Up to 32 devices per subnetwork Up to 32 subnetworks per RTU Up to baud per serial link (SAS900 and SAU900) Up to baud for the serial link velocity summation (*) Several protocols managed in the same time Signalling (RS), Controls (RC), Measurements (RM) Numerical protections synchronised by the RTU (*) per rack The maximum protection number managed by the RTU (all the rack) is equal to 256. It is possible to connect up to 32 relays per serial link. Due to the communication characteristics (polling) to assure a access time < 1s, we recommend to limit the number to 10 relays per serial link. The maximum velocity per serial link is 9600 baud. The sum of the communication links per rack shall be =< baud. It is not possible to transfer by the RTU disturbance or setting files from the relays. By using in K-Bus Courier communication protocol the KITZ201(2 separate link, 1 to the RTU and the other to a setting station) it is possible to provide a complete solution including remote setting.
