Platinum (385)
(1)
(1) The digits following the RTD type represent the temperature coefficient of resistance (α), which is defined as the resistance change per ohm per °C. For instance, Platinum
385 refers to a platinum RTD with α = 0.00385 ohms/ohm ·°C or simply 0.00385 /°C.

IMPORTANT
The exact signal range valid for each input type is
dependent upon the excitation current magnitude that you
select when configuring the module. For details on
excitation current, refer to page A-2.
