What it is and what it does
The MR-JE-200B: Communication is over SSCNET III/H with a cycle time selectable at 0.444 ms or 0.888 ms, which keeps it in sync with Mitsubishi motion controllers. The amplifier is force-cooled and rated IP20 (open type), so it needs clean, dry air inside the enclosure but sheds heat without a fan filter that clogs.
