OPERATING MODE
(*) We offer all devices who have a CONTACT CAPACITY of
min. 100 mA at 24 V DC with hard gold-plated contacts.
In this way the CONTACT CAPACITY of min. 100 mA is only 4 mA.

CONNECTION DIAGRAM
In use of the application below the simultaneousness of both switches is
monitored (less than 0,5 s). This behaviour corresponds to EN 954-1 safety
category 4.
This application is suitable for type II of DIN EN 574 and corresponds to EN 954-
1 safety category 3.
Wiring changes during operation are not allowed and lead to a failure message.
Application corresponds to EN 954-1 type IIIc and safety category 4, EN IEC
62061 up to SIL3 and EN ISO 13849-1 up to PLe.
