Connections
Analog Expansion Module connections are dependent on the application. Incorrect wiring may result in
damage to the module.
Notes
Operating power from the battery must be of the correct polarity. While
reverse polarity will not cause damage, the AEM-2020 will not operate.
Be sure that the AEM-2020 is hard-wired to earth ground with no
smaller than 12 AWG (3.31 mm
2 ) copper wire attached to the chassis
ground terminal on the module.
Terminations
The terminal interface consists of both plug-in connectors and a permanently mounted connector with
screw-down compression terminals.
AEM-2020 connections are made with one 5-position connector, two 12-position connectors, two 16-
position connectors, and two 2-position thermocouple connectors. The 16, 5, and 2-position connectors
plug into headers on the AEM-2020. The connectors and headers have dovetailed edges that ensure
proper connector orientation. Also, the connectors and headers are uniquely keyed to ensure that the
connectors mate only with the correct headers. The 12-position connector is not a plug-in connector and
is mounted permanently to the board. Connectors and headers may contain tin- or gold-plated
conductors. Tin-plated conductors are housed in a black plastic casing and gold-plated conductors are
housed in an orange plastic casing. Mate connectors to headers of the same color only.
