Compact Box

Compact Box modules are robust fieldbus stations for nine different fieldbus systems. They offer a wide range of I/O functionality. All relevant industrial signals are supported. In addition to digital and analog inputs and outputs including thermocouple and RTD inputs, there are also incremental encoder interfaces available for displacement and angle measurement in addition to serial interfaces to solve a large number of communication tasks. The digital inputs and outputs can be connected with snap type 8 mm diameter plugs, screw type M8 connectors, or with screw type M12 pendants. The M12 version is provided for analog signals.

Special input and output channels on the combination I/O modules can be used for either input or output. It is not necessary to configure them, since the fieldbus provides both input and output data for each combination channel. The combination modules give the user all of the advantages of fine signal granularity.

The processor logic, the input circuitry and the sensor power supply are fed from the box supply voltage, the auxiliary power for the outputs can be routed separately. In this way it is possible to achieve cascadable emergency off concepts. In Fieldbus Box modules in which only inputs are available the auxiliary power supply UP can optionally be connected in order to pass it on downstream.

The state of the fieldbus connection, the module status, the status of the power supply and of the signals is indicated by LEDs. The label strips can be machine printed elsewhere and then inserted.
