Schedule to EC Type Examination Certificate PTB 11 ATEX 2021 X
Output circuit Vcc-C ............................... in type of protection Intrinsic Safety Ex ib IIC
In-system, no external connection options
(terminal X1, contacts 4/17)
Output circuit Vcc-D ............................... in type of protection Intrinsic Safety Ex ia IIC
In-system, without external connection options
(terminal X1, contacts 1/20)
Under normal operating conditions, the output circuits Vcc-A and Vcc-C are to be con-
sidered as galvanically coupled with each other. They are safely galvanically isolated
from the input circuit Vcc-B up to a maximum peak voltage of 30 V.
The output circuit Vcc-D is safely galvanically isolated from all circuits up to a maximum
peak voltage of 60 V.
All output circuits are safely galvanically isolated from the supply circuit up to a maxi-
mum peak voltage of 60 V.
