Alstom 9000-4001 Ribbon changeover unit

Alstom 9000-4001 is a Starnet Microdrive ribbon changeover unit with two labelled ribbon paths. Its external terminal strip has 15 numbered positions. Relay A and Relay B supply connections are identified separately on the front panel. Transmit and receive terminal labels define the associated interface connections. The assembly supports the ribbon-cable changeover arrangement within the existing Starnet Microdrive installation. This legacy interface unit should be matched to its installed wiring and complete hardware identification before replacement.

The unit forms the changeover interface between the labelled ribbon-cable paths.

Dedicated transmit, receive and relay-supply labels organize the external connections.
