Resister Device Compatibility
The following table lists the specifications for the resistance devices that
you can use with the module.
Hardware Features The RTD/resistance module contains either a fixed terminal block (or a
removable D-sub connector) providing connections for four 3-wire inputs
for any combination of RTD and resistance input devices. Channels are
wired as differential inputs. The illustration below shows the hardware
features of the module.
