Functional Description
Contact Inputs
The CEM-2020 provides 10 programmable contact inputs with the same functionality as the contact
inputs on the DGC-2020. The label text of each contact input is customizable.
Contact Outputs
CEM-2020
The CEM-2020 provides 24 programmable contact outputs with the same functionality as the contact
outputs on the DGC-2020. Outputs 13 through 24 can carry 1 A. Outputs 25 through 36 can carry 4 A.
The label text of each contact output is customizable.
CEM-2020H
The CEM-2020H provides 18 programmable contact outputs with the same functionality as the contact
outputs on the DGC-2020. Outputs 13 through 24 can carry 2 A. Outputs 25 through 30 can carry 10 A.
The label text of each contact output is customizable.
NOTES
When using the DGC-2020 synchronizer, it is recommended that local relay
outputs on the DGC-2020 be used for breaker close commands to minimize
the possibility of closures outside of desired breaker closing angles.
If remote (CEM-2020) outputs are to be used for breaker close commands, it is
recommended that the anticipatory synchronizer type be used, and the breaker
close wait time be adjusted to account for possible CEM-2020 output delays
(typically 50 ms) to achieve desired breaker closing angles.
Communications
CAN Bus
A Control Area Network (CAN) is a standard interface that enables communication between the CEM-
2020 and the DGC-2020.
