Optionally, additional cards can be integrated in the versions 4 analog inputs and 8 relay outputs.
Analog input cards have blue terminals for better differentiation. The following sequence is used while
arranging the additional cards. Relay cards are always arranged first, starting from the rear on the
right (slot with the highest terminal number) in descending order. Analog input cards are then added to
the left of them in the direction of the (slots with the lowest terminal number).
Example:
If 3 analog input cards and 2 relay cards are installed in a fault annunciator with 40 inputs, the two
relay cards are located in the slots X38, X36 and the analog input cards in the slots X34, X32 and
X30.
However, if only 2 analog input cards and 2 relay cards are installed, the two relay cards are located in
the slots X38, X36 and the analog input cards in the slots X34 and X32. Slot X30 is not occupied.
