The binary inputs and output relays are freely configurable. When configuring these components it is important to note that the contact rating of the binary I/O modules (X) varies (see Chapter “Output Relays”). Once the user has selected a bay type, the P632 can automatically configure the binary inputs and output relays with function assignments for the control of switchgear units. The standard configuration of binary inputs and output relays for each bay type is given in the list of bay types to be found in the Appendix (see Chapter “Key to the List of Bay Types”, Chapter “List of Bay Types”).

The polarity for connected binary signal inputs is to be found in the terminal connection diagrams (see supporting documents supplied with the device or in Chapter “Location and Connection Diagrams”). This is to be understood as a recommendation only. Connection to binary inputs can be made as desired.
