Control device and accompanying control method for controlling an electrical device

摘要

The device (1) has channels (8) for forwarding a control command to a control electronics (4) by a switching element i.e. optocoupler, in an input electronics (7). A detection unit detects whether the control command, which is not represented in a series of an incorrect state of the channels, is transmitted. One of the channels is connected with a control unit (5), without an intermediate circuit of the control electronics, where the former channel acts on the control unit in a predetermined manner. The control electronics is signalized by a monitoring device (12). An independent claim is also included for a method for controlling an electrical device.
