Page 8: Function Description
SE-SR2 Function Description The relay SE-SR2 provides a safety-oriented interruption of a safety circuit. When operating voltage is supplied the "POWER" LED will light up. The unit is ready for operation when the start circuit S12-S34 is closed. Input circuit is closed (e.g. light grid not interrupted): –... -

Page 16: Safety Characteristic Data
PAScal software tool to calculate the safety function's SIL/PL values. Supplementary data CAUTION! It is essential to consider the relay's service life graphs. The relay outputs' safety-related characteristic data is only valid if the values in the service life graphs are met. Operating instructions SE-SR2 826002433-EN-Rev.C... - Page 17 If the service life graphs are not accessible, the stated PFH value can be used irrespective of the switching frequency and the load, as the PFH value already considers the relay's B10d value as well as the failure rates of the other components.
