Versatile Communication Unit (VCU)
The Versatile Communication Unit (VCU) is the gateway that not only connects the SASensor's Central Control Units with the remote control centre for remote operation and maintenance, but also with the office for continuous access to all digital information from the substation.
The configuration of the VCU depends on the requirements. It can include RS-232 ports for connection to e.g. remote control centres (RCC), UTP ports for connection to e.g. the Wide Area Network (WAN) and ST fiber optic ports to enable 100Base-FX Ethernet communication with the SASensor's Central Control Unit(s).
Optionally, the VCU can have a connection for the external GPS (Global Positioning System) antenna, to be used for absolute time accuracy.
