The bus connection module type SPA-ZC 17 converts the optical signals of the SPA bus to electrical RS 485 or SPA (+5 V) level signals and vice versa.
SPA-ZC 17 is provided with a built-in power unit allowing the SPACOM device to be disconnected from the bus connection module, for instance, for service without interrupting the data communication over the optical loop.
The bus connection module is mounted in a suitable place in the apparatus cabinet and the connection cable of the module is plugged to the D-type subminiature connector on the rear panel of the SPACOM device. The bus connection module type SPA-ZC 17 connects to any SPACOM device provided with a D-type subminiature connector.
Separate mounting accessories are available for mounting the bus connection module to a SACO data communication and reporting system.
