ABB NPSI02 Module Power Supply

Model Type: Bailey Net 90 Power Supply

Bus connection module SPA-ZC 22 The bus connection module SPA-ZC 22 is used for dividing the system into several fibre-optic loops.

The SPA-ZC 22 module is available in two versions, one with five fibreoptic transceiver pairs and one with two pairs. 

The SPA-ZC 22 module is connected to the communicator units of the SPA loop. 

The bus connection module features a built in RS 232 C interface for direct connection to a PC,

a modem, etc. and one RS 485 interface for connection to e.g. a SRIO unit.

The bus connection module can also be used in slave mode if a double connection to one substation secondary device is needed.

The third mode of operation for the SPA-ZC 22 module is the optical repeater mode.

In the optical repeater mode a fibre pair from the communicator unit's optical module is

connected to the first transceiver pair of the SPA-ZC 22 module.

The data is then retransmitted over the other transceiver pair(s) in the module. 

The bus connection module SPA-ZC 22 is powered form the device to which it is connected or from an external power source.
