There is information in the price list that the number of channels may be reduced to 4. I reviewed the manual and wiring diagram of the AI module. It seems that there is no harm in connecting Pt100 to 8 channels. Can you please confirm? Best regards. Wiring of 3-wire RTD with 6ES7531-7QF00-0AB0 Attachment Image.png (187 Downloads)

(Page 17 for resistance sensors) You can use 2-wire and 3-wire sensors, and then you will have 8 channels. Best regards, Wizard
