The SPA-ZC 102 is a LON/SPA gateway module which is provided with its own power supply. It operates in the same way as the SPA-ZC 100 module, but can also be used with a fibre-optic converter, e.g. SPA-ZC 21.
The SPA-bus device to which this module is connected can be any protection relay, control module or alarm annunciator, which has an interface for the SPA bus (RS-485, RS-232 or logic/TTL interface). The SPA interface type is selected with the DIP switches located between the D9 connector and the fibre-optic connectors. The SPA-ZC 102 module contains a power supply and it is capable of supplying the SPA-ZC 21 converter.
