3ACTR to P1-08ADL-1 wiring
The manual for the 3ACTR isn't 100% clear but would I be correct in assuming + terminals 1, 3, 5, and 7 gets connected to +24V and - terminals 2, 4, 6, and 8 get connected to the P1-08ADL-1 inputs. Terminals 9 and 10 go to 24V and com and are not polarity sensitive

The below link will take you to the Q&A for a Click C0-04AD-1. However, should still apply to P1-08ADL-1. This is because the outputs are loop-powered True RMS.

Do I disregard
"Note: Power supply and output signal ARE NOT isolated. Do not connect the negative terminals to a common point."
and wire 2, 4, 6, and 8 to 24 com
This just means that there is no isolation between the power input (terminals 10 and 9 are the power supply terminals) and the output terminals. As long as you are wiring to your PLC input card directly there should not be any issues. If you are using the same power supply there is a risk of ground loops that could mean the signal would be incorrect because some of the current could flow through a different path (ground loop). Won't be an issue if you have your output loop wired directly to an analog input card.
If using the same power supply for the analog input module and the Acuamp I would put the output of the AcuAmp before the input card. So 24V to the AcuAmp and the negative side to the input of the card. The current would flow through the card and out the 0V side of the card to the power supply. Should not have any ground loop issues that way.
