The voltage relay SPAU 331 C can be connected
to the optical fibre SPA data bus by means of a
9-pole D type connector located on the rear
panel of the voltage relay, and a matching bus
connection module type SPA-ZC_. The opto-

the counter connectors Rx and Tx of the bus
connection module and the optical fibres are
linked from one protection relay to another and
to the control data communicator.
