COMPONENT CHARACTERISTICS
DOOR SWITCH:
SAFETY SWITCH, designed in compliance with the standard currently in effect IEC60947,
EN292, EN60204, EN1088. Two redundant contacts. IP67. B10d=2000000.
SAFETY LOGIC:
main component SAFETY PLC min. PLd according EN13849-1. Output type relays, min
10mA. To be installed in an IP54 enclosure.
CONCLUSIONS
Because MTTFd is greater than 100 years, Category is 3, max achievable DC is 99%, so this example
satisfies the PLr=c.
