4.3.3.1.3 Single-pole switching relay or semi-conductor output with dual-channel external circuit
with testing
For safety applications from PI c and higher acc. to EN ISO 13849-1 we strongly recommend or
even demand the control of two external cutout elements. Furthermore, the setup for testing the
complete chain and a message/warning device for an detected fault is required for achieving PI
c or higher - see also remarks under 4.3.3.1.2.
