Compact safety relay meets standard requirements up to
PL e (ISO 13849-1) and SIL 3 (IEC 62061)
To monitor emergency stop and protective door circuits, as well as for evaluating photoelectric barriers, the PSR-ESD-30 multifunctional safety relay offers two undelayed and two drop-out delayed contacts.
Here, except for choosing a delay time from 0.1 to 30 seconds, no settings are required on the thin 22.5 mm device. Manipulation of the set time during running operation is prevented by built-in control logic.
In addition to the safety category 4 requirements in accordance with EN 954-1, the PSR-ESD-30 also meets the new safety standards ISO 13849-1, EN 62061 and IEC 61508 and can therefore be used in all applications requiring a reliable time function.
Thanks to the manufacturer specification of performance level e, ISO 13849-1 users don't have to do complex calculations. In accordance with EN 62061, the safety relay with SILCL 3 and a PFH value of 2.07 x 10 E -9 is suitable for the highest safety requirements.
