Title:
電気負荷のフェールセーフ停止用の安全切換装置およびその方法
Document Type and Number:
Japanese Patent JP2007500427
Kind Code:
A
Abstract:
The invention relates to a safety switching device for the failsafe shutdown of an electric load, such as an electrically driven machine. The safety switching device has a signal processing part for receiving and evaluating an input-side switching signal, which, for example, originates from an emergency stop switch. It also has at least one switching element which, controlled by the signal processing part, provides an output-side switching signal for shutting down the load. An anti-surge element is provided for canceling reaction voltage spikes when the load is shut down. The anti-surge element has at least a first and a second anti-surge operating mode, which can be activated as an alternative to one another.
