short circuit proof
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.
Please ask our sales team!
CONNECTION DIAGRAM
Even ESPE type 4 with OSSDs and relay contacts as well as ESPE type 2 with
one OSSD and test input are supported. Monitoring of movement direction is
available by different simultaneousnesses.
