Caution
By mating conductors of dissimilar metals, galvanic corrosion could
occur which may lead to signal loss.
Connector screw terminals accept a maximum wire size of 12 AWG (3.31 mm 2 ). Thermocouple
connectors accept a maximum thermocouple wire diameter of 0.177 inches (4.5 mm). Maximum screw
torque is 5 inch-pounds (0.56 N

m).
Operating Power
The Analog Expansion Module operating power input accepts either 12 Vdc or 24 Vdc and tolerates
voltage over the range of 6 to 32 Vdc. Operating power must be of the correct polarity. While reverse
polarity will not cause damage, the AEM-2020 will not operate. Operating power terminals are listed in
Table 84.
It is recommended that a fuse be added for additional protection for the wiring to the battery input of the
Analog Expansion Module. A Bussmann ABC-7 fuse or equivalent is recommended.
