For your Micrologix1400 PLC (hey everyone, I'm clairvoyant
) you'll need an analog input module. The module you'll need depends on the model of IR thermometer you choose.
Don't mess with the 10mV/C output models, those are for pen recorders and not the best fit for a PLC.
If you choose an IR thermometer with a type K T/C output you'll need a 1762-IT4 module. (Only choose this one if you have other standard thermocouples and already have an 1762-IT4 card.)
If you choose an IR thermometer with a 4-20mA output you'll need a 1762-IF4 module (4 inputs) or a 1762-IF2OF2 (2-in, 2-out).
If you choose an IR thermometer with a 0-5 or 0-10V output and your ML1400 is a 1766-L32BWA, 1766-L32AWA, or 1766-L32BXB model then you'll need a 1762-IF4 module (4 inputs) or a 1762-IF2OF2 (2-in, 2-out). If your PLC is a 1766-L32BWAA, 1766-L32AWAA, or 1766-L32BXA then you can use one of the on board analog inputs and you don't need an expansion module as long as you can live with 10 bit resolution.
After you choose the IR thermometer model get the manual from the AB website for the matching analog IO card and refer to it for wiring and module configuration info.
Add the module to your program in RSLoigx500 under IO Configuration in the project tree.
In your PLC program you'll need to scale your mA or Voltage input to the temperature range of the IR thermometer. Use the SCP instruction to do this.
(p.s. I'm not really Clairvoyant, because I was feeling charitable I just spent the time to dig through the OPs other posts till I figured out what PLCs he was using)
Plan A, plead elegant ignorance and beg for no-cost exchange or reduced restock fee. You may have to eat any shipping charges too, but it's a small price to pay for the right end result.
