Below is a document to help explain how our Mpltiplex Expansion board works in it's various configurations - (01-17145-1 PLUTO 256 LAMP/LED EXP).

It can run in various Duty cycles, and upto 256 Lamps or LED's or a combination of the two -
It can be a bit tricky to get the config correct as it depends on the Power supply input and the nu,ber of LED's or Lamps you wish to run in your application, hopefully this will help -

If you need any more info, help or sample boards to test, just let us know.

They work on Pluto 5 and Pluto 6 and Pluto 8 and Xluminate and give further expansion capacity.
