EUCHNER MSC - Safety Relay (Az-Fo4;Az-Fo4 O8); Characteristics of the Output Circuit

English
Automatic
The output is only activated, as per the configuration defined by EUCHNER Safety De-
signer, if 24 VDC are applied to the related input RESTART_FBK.
Manual
The output is only activated, as per the configuration defined by EUCHNER Safety Designer,
if there is the logical transition 0-->1 on related input RESTART_FBK.
Monitored
The output is only activated, as per the configuration defined by EUCHNER Safety Designer,
if there is the logical transition 0-->1-->0 on related input RESTART_FBK.

SAFETY RELAY (AZ-FO4/AZ-FO4O8)
Characteristics of the output circuit
The modules AZ-FO4/AZ-FO4O8 have safety relays with positively driven contacts with
1 normally open contact and 1 normally closed feedback loop contact. The modules
AZ-FO4/AZ-FO4O8 contain 4 safety relays.


To ensure correct isolation and to prevent the risk of premature aging or damage to
the relay, each output cable is to be protected using a 4 A quick-blow fuse. In addi-
tion, the load characteristics must correspond to the information in Table 15.
