GFK-1504N Chapter 14 Temperature Sensing Modules 14-7
IC200ALG620
Analog Input, 16 Bit RTD, 4 Channels
Configurable Parameters
The default parameters of the RTD Input module can be used in many
applications. The module can be software-configured when it is installed in a
VersaMax PLC system or an I/O Station controlled by a NIU that is version 2.0
or above.
