- 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
 
Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.
 
notice - Wiring example
 
The example shows a 2-channel control of 2 muting sensors and an external master reset button.
Relay outputs: Suitable for 2 channel control, for increase in capacity or number of contacts by means of contactors or relays with positive-guided contacts.
(H2) = Feedback circuit
The control recognises cross-short, cable break and earth leakages in the monitoring circuit.
F1 = Electronic fuse
The wiring diagram is shown with non-actuated muting sensors and in de-energised condition.
