9-2 DGC-2020 CEM-2020 (Contact Expansion Module) 9400200990 Rev I
HALT (Highly Accelerated Life Testing)
HALT is used by many manufacturers to prove that their 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 CEM-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 CEM-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 Section 9 of this manual.

FUNCTIONAL DESCRIPTION
Contact Inputs
The CEM-2020 provides 10 programmable contact inputs with the same functionality as the contact
inputs on the DGC-2020.
Output Contacts
The CEM-2020 provides 24 programmable output contacts with the same functionality as the output
contacts on the DGC-2020. Outputs 13 through 24 can carry 1 A. Outputs 25 through 36 can carry 4 A.
Communications
CANBus
A Control Area Network (CAN) is a standard interface that enables communication between the CEM-
2020 and the DGC-2020.
