The active module DC-I is needed in the 24 Vac/dc power supply version to form an active current or
pulse output in combination with one of the passive modules P-SA or FA-ST. Due to limited space it is
not available for 100...230 Vac supply versions.

Due to mechanical and electrical limitations, only the 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 with DC-I or FA-ST
with DC-I is made internally.
The flameproof terminal feed-through has seven terminals in total, the top two terminals are used for
connection of the power supply, the third one is only used for mounting of a metal dividing plate with
insulating cover plate. The remaining four are used for the intrinsically safe signal in-/output circuits of
the installed MODIS modules.
The metal dividing plate and the insulating cover plate warrant the required separation distances (i.e.
clearances, creepage distances and distances through insulation) between the non-intrinsically safe
power supply terminals and the intrinsically safe signal in-/output circuits. The insulating cover plate is
provided with a sticker that contains important instructions how to remove and re-install the cover plate
and the conditions under which it should be established (circuits not live !).
Important !
Carefully follow the instructions on the sticker that is glued to the top of the insulating
cover plate that covers the non-intrinsically safe power supply terminals !
