System Connections

Connection between OPAL-RT’s simulator and OP8660 conditioning module

OPAL-RT’s simulators compatible with the RCP-EC2K kit offer in their back and front panels access to a broad array of IO ports which can be flexibly customized and assigned as needed by the user. However, the RCP-EC2K kit has been conceived to allow users to quickly interface the OPAL-RT simulator with the OP8660 signal conditioning module.

Interfacing the OPAL-RT simulator with the OP8660 is straightforward: the compatible DB-37 connectors of both the simulator and the OP8660 are clearly identified with matching Quick Connection labels that must be connected using the provided DB-37 cables, as shown in Figure 3.1 for the OP56001. Table 3.1 indicates the connections to be performed and the signals contained on each connector.
