Table 10: IFC 090i-EEx 100-230 Vac versions.
Due to mechanical and electrical limitations, only the in table 9 and 10 listed pairs of MODIS
modules are possible. The two modules each use two terminals of the bottom four terminals
of the flameproof terminal feed-through in the dividing wall between the electronics and
terminal compartment of the signal converter housing, except for the combination with
module DC-I (only applicable for 24 Vac/dc versions), where only two of the four terminals
are used. Interconnection of the two modules, P-SA and DC-I resp. FA-ST and DC-I is made
internally.
