Maintenance & Test Equipment
The D-dock system consists of a D-dock Test Block which is put between the existing relay socket and the existing D-U plug-in relay. All 14 relay-pins are wired to the Break-Out Box enabling to connect measuring equipment like multimeters, scope meters or data analyzers to log operations during longer period. This makes fault finding easy. The D-dock fits in tightly packed relay panels and small cabinets. It can operate unattended enabling normal passenger operating service.
