We use a lot of the P3-32TD2 and P3-64TD2 output modules using the ZL-CBL40 cables to a ZL-RTB40 break-out module. We then use a ZL-CBL24-1P from a ZL-RRL16F-24-2 relay modules to the ZL-RTB40. Works good but it would be nice to have a version of the ZL-CBL40 cables that would split out to two connectors for the ZL-RRL16 relay modules. Hope this makes sense it would make my life a little easier LOL.
