Redundant AAM50/AAM51
These modules output signals of 4 to 20 mA or 0 to 10 V.
They may be made redundant when they are set in the current output mode.
To make them redundant, two AAM50 or AAM51 modules must be installed in two adjacent
slots beginning with an odd-number slot (1-2, 3-4, ....13-14, 15-16) and set to be redundant,
and adjacent terminals A and C must be connected to check their outputs against each other as
shown below.
The AAM50 and AAM51 modules cannot be combined for redundancy.
