Scaling a 4-20mA Analog Input in an Allen Bradley PLC Ladder Logic

We show you how to scale your 4-20mA analog input in Studio 5000 ladder logic. We will use a CPT compute instruction and the y=mx+b slope intercept formula we learned in the last lesson. This example is in Studio 5000 / RsLogix 5000 for the Controllogix and Compactlogix PLC but this sample equation will work with most PLCs.
