Overview of CG30 numbers with EEx ia in/outputs
Notes :
- shorts for in/output functions:
CO= current output, PO=Pulse Output, SO= Status Output, CI= Control Input,
PA=Profibus PA, FF=Foundation Fieldbus, DP=Profibus DP
- all in/outputs are passive unless otherwise noted as active (a)
- n.c. is not connected
The IO circuits named Ex i IO, Ex i Option are always in type of protection Intrinsic
safety (EEx ia). The IO circuits Fieldbus IO Profibus PA and Fieldbus IO Foundation
Fieldbus
can
be in type of protection Intrinsic safety.
A maximum of 4 intrinsically safe (EEx ia) in/outputs are possible. All intrinsically safe
circuits are galvanically insulated with respect to earth and to each other. To avoid
summation of voltages and currents, the wiring of the of these EEx ia circuits must be
sufficiently separated, e.g. in line with the requirements of standard EN IEC 60079-
14, section 12.2.
