The new redstone fader pluggable is a replacement for the redstone fader gate expansion. This pluggable is used to measure the in world adjacent redstone wire level and use that state for other gate actions

The redstone fader expansion had two iterations found in 7.1.x and 8.0.x-old and is up for discussion how this expansion should be implimented:

7.1.x (https://github.com/BuildCraft/BuildCraft/tree/7.1.x):

• Has one gate trigger and action for each level of redstone 1-15

8.0.x-old (https://github.com/BuildCraft/BuildCraft/tree/6afa101c7248b3a505af5f5f3d2ddece07341fb7):

• Has three gate triggers which consist of: Redstone equal to, Redstone greater than and Redstone less than
• These triggers use the previous redstone levels triggers as parameters to determine what the signal should be greater to/ equal to/ less than etc.

As for the model, I have no idea ¯_(ツ)_/¯

Feel free discuss which of the two ways you think this pluggable should work down below and which you would prefer cc @asiekierka

By all means the 8.0.x-old variant!
