Dual-channel switching relay output with external monitoring – collective feedback
The two external monitoring contacts are connected in series, supplied with pulse signal T0
and read by I00 (configured as EMU input). With increased requirements, it is to be noted that
at least 1 switching process must take place at least every 24 hours.
Safety instructions:
 An adequately high test rate is required to achieve PL e according to EN ISO 13849-1.
 For applications with frequent demand for the safety shutdown, testing should be at
short intervals, e.g. at the start of the shift, 1x per week. However, a test should be
undertaken cyclically at least 1 x per year.
