cd80sv

Hi everyone,Has anyone had experience with replacing/repairing Strand's CD80SV "Z" Type 2.4kW Non-Dim Relay modules? My high school has had 2 of these units fail, in one of them both relay control boards have failed and in the other one only one board has failed. Is there an easy way to repair...

Does anyone have a working CD80SV rack processor card still hanging around somewhere that they'd like to sell?My processor card had a pretty significant corrosion event related to a battery leak during Covid downtime, and my dealer took a look at it on the bench and decided it wasn't...
