Analog Expansion Module DECS-250
Communication Interface
The AEM-2020 communicates with the through CAN1.
CAN Bus
Differential Bus Voltage .............. 1.5 to 3 Vdc
Maximum Voltage ...................... –32 to +32 Vdc with respect to negative battery terminal
Communication Rate .................. 125 or 250 kb/s
Type Tests
Shock
Withstands 15 G in 3 perpendicular planes.
Vibration
Swept over the following ranges for 12 sweeps in each of three mutually perpendicular planes with each
15-minute sweep consisting of the following:
5 to 29 to 5 Hz ............................ 1.5 G peak for 5 min.
29 to 52 to 29 Hz ........................ 0.036” Double Amplitude for 2.5 min.
52 to 500 to 52 Hz ...................... 5 G peak for 7.5 min.
HALT (Highly Accelerated Life Testing)
HALT is used by Basler Electric to prove that our products will provide the user with many years of
reliable service. HALT subjects the device to extremes in temperature, shock, and vibration to simulate
years of operation, but in a much shorter period span. HALT allows Basler Electric to evaluate all possible
design elements that will add to the life of this device. As an example of some of the extreme testing
conditions, the AEM-2020 was subjected to temperature tests (tested over a temperature range of –80°C
to +130°C),
vibration tests (of 5 to 50 G at +25°C), and temperature/vibration tests (tested at 10 to 20 G
over a temperature range of –60°C to +100°C). Combined temperature and vibration testing at these
extremes proves that the AEM-2020 is expected to provide long-term operation in a rugged environment.
Note that the vibration and temperature extremes listed in this paragraph are specific to HALT and do not
reflect recommended operation levels. These operational ratings are included in the Specifications
chapter of this manual.
