Abstract
An ethernet switch includes a housing that has at least one communication input for data of a controller, at least one system input for a system voltage and at least one communication output. At least one voltage output to an electrical load is also provided. A power supply unit, which provides the voltage supply for the switch, is provided in the housing of the switch. The power supply unit also feeds the at least one voltage output to an external load. A field bus element, which is preferably configured to monitor and/or to control the voltage output to an external load, is integrated in the housing of the switch.
Claims16
An ethernet switch comprising:
- a housing having at least one communication input for data of a controller, at least one system input for a system voltage, and at least one communication output;
- at least one electrical supply output configured to connect to an electrical load;
- a power supply unit disposed in said housing;
- said power supply unit having a primary side and being connected to the system voltage at said primary side, wherein the system voltage is 90 Volts to 800 Volts;
- said at least one system input for the system voltage being looped through to a system output provided in said housing for the system voltage;
- said system output being configured to connect a further switch;
- said power supply unit being configured to provide a voltage supply for the ethernet switch;
- said power supply unit being configured to feed said at least one electrical supply output to an external load with an output voltage of said power supply unit;
- and,
- a field bus element integrated in said housing and configured to at least one of monitor and control said at least one electrical supply output to the external load.
