CONTACT SECURITY

3,6A

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

When releasing E-Stop button or opening the safety gate (E-Stop circuit are

open) the contacts 13-14 and 23-24 (outputs) open. The contacts 47-48/57-

58 open delayed at the adjusted time.

SAFE TN standby time after applying of the supply voltage < 0,95 s.

Opening of

the E-Stop circuits meanwhile results to failure.

SAFE TA standby time after applying of the supply voltage < 0,95 s.

Opening of

the E-Stop circuits meanwhile results to several activations of the

outputs after the standby time.

SAFE TR restart is possible during standby time.

SAFE TU standby time after applying of the supply voltage < 0,95 s.

Opening of

the E-Stop circuits meanwhile results to several activations of the

outputs after the standby time.
