Functional Description
A functional description of the AEM- 2020’s inputs and outputs is provided below.
Analog Inputs
The AEM-2020 provides eight analog inputs that are user-selectable for 4 to 20 mAdc or 0 to 10 Vdc.
Each analog input has under/over thresholds that can be configured as status only, alarm, or pre-alarm.
When enabled, an out of range alarm alerts the user of an open or damaged analog input wire. The label
text of each analog input is customizable.
RTD Inputs
The AEM-2020 provides eight user-configurable RTD inputs for monitoring genset temperature. Each
RTD input can be configured as status only, alarm, or pre-alarm to protect against high or low
temperature conditions. When enabled, an out of range alarm alerts the user of an open or damaged RTD
input wire. The label text of each RTD input is customizable.
Thermocouple Inputs
The AEM-2020 provides two thermocouple inputs for monitoring genset temperature. Each thermocouple
input can be configured as status only, alarm, or pre-alarm to protect against high or low temperature
conditions. The label text of each thermocouple input is customizable.
Analog Outputs
The AEM-2020 provides four analog outputs that are user-selectable for 4 to 20 mAdc or 0 to 10 Vdc. A
wide selection of parameters including oil pressure, fuel level, generator voltage, and bus voltage can be
configured as analog outputs.
Communications
A Control Area Network (CAN) is a standard interface that enables communication between the AEM-
2020 and the DGC-2020HD.
Mounting
Analog Expansion Modules are delivered in sturdy cartons to prevent shipping damage. Upon receipt of a
module, check the part number against the requisition and packing list for agreement. Inspect for
damage, and if there is evidence of such, immediately file a claim with the carrier and notify the Basler
Electric regional sales office, your sales representative, or a sales representative at Basler Electric,
Highland, Illinois USA.
If the device is not installed immediately, store it in the original shipping package in a moisture- and dust-
free environment.
Analog Expansion Modules are contained in a potted plastic case and may be mounted in any convenient
position. The construction of an Analog Expansion Module is durable enough to mount directly on a
genset using ¼-inch hardware. Hardware selection should be based on any expected
shipping/transportation and operating conditions. The torque applied to the mounting hardware should not
exceed 65 in-lb (7.34 N

m).
See Figure 186 for AEM-2020 overall dimensions. All dimensions are shown in inches with millimeters in
parenthesis.
