Technical data for EE300Ex (extract from the EU-Type Examination Certificate):
Certified according to:
II 1G Ex ia IIC T4 Ga
II 1D Ex ia IIIC T80°C Da
Entity parameters:
U
i
= 28V
I
i
= 100mA
P
i
= 700mW
C
i
= 2.2nF
L
i
= negligibly small
Proof of the intrinsic safety according EN 60079-11:2012
EN 60079-25:2010 (Appendix A)
U
0
= 27V ≤ U
i
= 28V → ok
I
0
= 88mA ≤ I
i
= 100mA → ok
P
0
= 576mW ≤ P
i
= 700mW → ok
C
0
= 90nF ≥ 2,2nF + 33nF → ok
L
0
= 2,3mH ≥ 0mH + 0,195mH → ok
Conclusion: The protection level of the intrinsically safe current circuit is met.
Proof of the intrinsic safety according EN 60079-11:2012,
EN 60079-25:2010 (Appendix A)
L
i
= negligibly small → no reduced C
0
and L
0
values are required.
4.7 Configuration Adapter
The on-board service interface is dedicated for the EE300EX configuration and for the RH and T adjust-
ment. This is possible by the optional EE-PCA Product Configuration Adapter and HA011068 connec-
tion cable. Refer to datasheet EE-PCA and HA011068 user manual.
The EE-PCS configurator software and the drivers are available for download free of charge at

mixed electric circuits
For intrinsically safe electric circuits with
linear sources, simplified evaluation rule:
each half value of C
