Could someone be kind enough to clarify this diagram to me on Page 53 of this PDF (http://literature.rockwellautomation.com/idc/groups/literature/documents/um/1734-um001_-en-p.pdf)?
It shows the signal going into Ch0 but there is no connection for L1/N, only L1. So how does the module have a neutral reference? The module is on an AENT which is 24VDC power. I built this on Rockwell's IAB, too, and it doesn't mention a need for a 1734-FPD, so I really don't understand how sending a 120vac signal is going to trigger an input to this module. I am used to the 1756-IA16 where there are neutral points for reference.
Thanks.
