QUESTION:

If multiple EMERGENCY STOP command devices are electrically connected in series, is each safety-related shutdown via an EMERGENCY STOP command device a single supplementary safety function in compliance with IEC 62061?

 

 

ANSWER:

IEC 62061 – Application explanation:
If several EMERGENCY STOP command devices are electrically connected in series, each safety-related shutdown via an EMERGENCY STOP command device is a single supplementary safety function.

In the attachment you will find a document that explains the subject matter in detail.
