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 Network Interface Unit that is version 2.0 or above.
