Classification
 
StandardsEN ISO 13849-1, IEC 61508, EN 60947-5-1
PFH value≤ 2,0 x 10-8/h (STOP 0)
Mission time20 Years
- noticeThe PFH value is applicable for the combinations listed in the table for contact load (K) (current through enabling paths) and switching cycle number (n-op/y).
In case of 365 operating days per year and a 24-hour operation, this results in the specified switching cycle times (t-cycle) for the relay contacts.
Diverging applications on request.

notice - Wiring example
 
Start configuration: 2 time-dependent reset/on switches 1st and 2nd monitoring time between the 1st and 2nd reset button from 3 … 30 seconds adjustable through DIP switches
The monitoring time is set through DIP switches located below the cover of the enclosure front. (Factory setting: 3 seconds)
Actuator configuration: 1-channel control (output impulse approx. 200 ms) of the reset input of a downstream safety relay module
(H2) = Feedback circuit
Edge detection: After the device is reset, the trailing edge is evaluated, so that errors, e.g. welded contacts or manipulations cannot lead to dangerous situations.
The wiring diagram is shown with guard doors closed and in de-energised condition.
