OP4200 General Pin Assignments

Conditioning cassettes come with either one (analog) or two (digital) DB37 connectors. These connectors respect OPAL-RT’s standard DB37 pinout, as shown in the table below.

Left: Channels 00-15
Right: Channels 16-31

The following tables provide the general pin assignments for the OP4200 connectors.

Detailed pin assignments for all connectors can be found in the System Description document provided with your order, or refer to the pin assignment of the OP5300 series IO module associated with each DB37F connector.

Before designing cables, OPAL-RT recommends using the guideline Simulator EMC caDB37 set of connectorsble recommendations.
