CEM-2020 Connections
The CEM-2020 (Contact Expansion Module) is an optional module that may be installed with the DGC-
2020ES. It is a remote auxiliary device that provides additional contact inputs and outputs for the DGC-
2020ES. This module interfaces to the DGC-2020ES via CAN, thus the CAN terminals are the only
common connections (Figure 55) between the DGC-2020ES and CEM-2020. Refer to the CEM-2020
chapter for more information.
Refer to Terminals and Connectors for details on DGC-2020ES CAN connections.
