GFK-1504N Chapter 14 Temperature Sensing Modules 14-9
IC200ALG620
Analog Input, 16 Bit RTD, 4 Channels
Input Selection to Include RTD Type
Each input channel can have a different RTD type. The module supports the
RTD types listed below. If the actual RTD resistance does not match a defined
type, an adjustment factor can be configured in tenths of Ω.
