Product Video


The Rail Control Unit (RCU) ANTARES is the central unit in the ANTARES system. It consists of the head module and the connection module. Various field bus and Ethernet-based head modules are available. There is no need to use an isolating repeater to connect them. Redundancy is achieved with no single point of failure by connecting two PROFIBUS-DP RCUs. The head module, consisting of the CPU, the communication interface and an integrated power supply unit, is produced with the Ex d type of protection and is plugged into the corresponding connection module. The innovative interlocking technology ensures a reliable connection. The hot swap capability allows the head module to be replaced even in an explosive atmosphere. The connection module has an integrated Ex e junction box. A version is also available for armoured leads. The system is configured by means of Software ANTARES Designer using the USB interface. See the system description for installation instructions.
