The voltage jumpers hatched
XXXX
in the figure are not used in the analog
module. This means that the 24V supply of the NIU (U

) or the power terminal are
electrically isolated from the I/O circuit (measurement amplifier) of the analog
module. The I/O circuit of the analog module is supplied by the analog circuit U
ANA
.
