OP7821 Solid State Relay Module
The OP7821 provides 16 isolated solid-state relay outputs that can operate up to 250V in both AC and DC configuration.
Channel Description
Each isolated output is a single-pole normally-open solid-state relay with an integrated current-limiting feature that can replace electromechanical relays while enhancing the robustness of wireline-interface applications.
The electrical circuit also implements thermal shutdown.
The dynamic characteristics and current limits of the channel are as follows:

Face Plate
The OP7821 faceplate holds one DB37F connector.
DB37F Pin Assignments
The connector respects OPAL-RT standard DB37 pinout.
