SACDT Wagon Series 26-16
The system implements an automation network in the wagon, composed of the vehicle bus (CAN network, CANopen protocol) and the train bus (WTB network, according to UIC 556).
The control part ensures the control of the doors, lighting, the minimum voltage relay (protection against battery discharge when the static source no longer works), the reception and processing of various analog signals (battery voltage, charging current, three-phase system voltage values, etc.), as well as the control of the passenger information system (information for interior and exterior displays).
The diagnostic part provides data about the controlled systems and collects diagnostic data from various subsystems (for example: the air conditioning and access door control unit) and transmits it to the first class wagon for centralization.
Additionally, a control unit for the heating and air conditioning (HVAC) system is delivered. The system is integrated through the design of the electrical installation and the electrical panel which is also made by Tehmin-Brasov.
