Safety Specifications

The MSR117T safety relay can be used in safety circuits according to 
DIN EN 60204-1/VDE 0113 part 1. Safety requirements that are specified in 

Specification on page 1

 are maximum, based on the operation mode and wiring.

Specifications are applicable only if the safety function is demanded at least once 
within 6 months. Conduct all diagnostic tests at least before the next demand, as 
mission time (TM) the proof test interval (PTI) is assumed. Components failure 
rates are according to SN29500.
