I can not craft the conveyor module, i am using 3 glass on top, 3 refined iron in the middle a electronic circuit in the bottom left and right with a battery in the bottom middle. I tried using a charged battery too without result.
I am playing "vanilla" FTB unleashed, i just installed it without turning any extra's on or off.
There is no info at all about this module: http://feed-the-beast.wikia.com/wiki/Conveyor_Module

If neither of the recipes work for you, there is a high chance you don't have the GregTech mod. The newest FTB version (Unleashed, 1.1.3) don't seem to have it, if I'm looking at the mod list correctly. You might try moving a bit backwards to 1.1.2 or 1.1.0.
Another solution might be adding the mod yourself, but there is always the possibility of it not being compatible. If you want to go this way, download it through a link on the wiki page and click Edit mod pack while having the pack you use selected. Afterwards, just find the downloaded files and add them.
