Module is a 1U tile.
No info about availability.
1U Tile slew limiter.
This Tile slews the input signal according to the pot setting, and sends it to the output. On the rear of the unit is a dip switch which sets the slew range from very slow to very fast (see picture). It may be desirable to have a couple of Slew Tiles in a system with different range settings on each.
These merchants probably sell this module. Huh?
