CZAT7 controller

The CZAT7 controller is a PLC automation device, created to work in demanding and specific conditions of rail and tram electrical power engineering. The device is freely programmable and has been designed in accordance with the applicable standards for microprocessor controllers. CZAT7, depending on the prepared application layer, can be used as an automation or telemechanics of various elements, devices and subsystems of the traction substation, creating one integrated substation automation system (station system).

CZAT7 controller

The most characteristic places to use the CZAT7 controller’s capabilities are rail and tram DC switchgears. Individual devices are connected to each other with the IEC 61850 Standard or via a parallel CAN bus and using the PPM2 transmission protocol. 

System architecture

CZAT7 controllers are modular in build. The basic unit consists of a central processing unit (CPU), a power supply module (PSU) and at least one slave input/output module (DOU, DIU, DIOU). This is the optimum solution, because it allows one to adjust the system to specific needs, its further expansion and execution of modernization work in stages. The basic unit can optionally also be equipped with an HMI panel (CZAT Synoptic), supporting local control of particular devices (e.g. a single field).
