摘要
A safety module for a field-bus system comprising a switch-on unit, a control unit, a supply input provided to feed supply power, a first supply output provided to relay secured supply power to a consumer, a first switching element to electrically connect or disconnect the supply input and the first supply output, and a supply module to provide an operating power via an operating-power-supply line for operating the control unit. The control unit is connected to the first switching element to secure the supply power being relayed via the first supply output by actuating the first switching element. The supply module is electrically connected to the supply input and to a field-bus-power input. The field-bus-power input is provided to feed a field-bus power into the safety module for operating the switch-on unit. The supply module is provided to generate the operating power either from the supply power or field-bus power.
