Exist any module to put one analog input and 3 outputs with the same signal? Thanks ! Splitted from Connect analog input to Logo! and DataLogger.

However you can have two analugue input modules and a separate output module on the same logo installation. Alternatively you could multiplex your inputs, and use a relay (or relays) controlled by the logo to switch different signals to the single input module.This approach takes time and limits the band width of each signal that you will be able to "see". It also introduces a degree of "data scew" which might give you problems if your process requries you to consider the values of the inputs at the same instant. If you'd like to know a bit moreplease ask.

This inputs you can use to connect analog sensors. Then you only need an additional AM2 AQ. So you have 4 AI (onboard) and 2AQ's at the EM. Hope this helps
