23.13.6 Analog Input Configuration
Some analog inputs are multi-purpose capable and have several configuration options. These inputs are
configured by the GDU (refer to
GDU 45X/46X systems) and are capable of reading any voltage up to 40 Vdc.
NOTE
If installing an ungrounded thermocouple to an Analog In input, a DC reference must be
added to the LO input. This can be accomplished by adding a resistance of 1 MΩ or less
between ground and the Analog In LO input that the ungrounded thermocouple is installed
on.
