4.9 S8 RTD TEMPERATURE 4.9.1 RTD TYPES
Each of the twelve RTDs may be configured as None or any one of four application types, Stator, Bearing, Ambient, or
Other. Each of those types may in turn be any one of four different RTD types: 100 ohm Platinum, 120 ohm Nickel, 100 ohm
Nickel, 10 ohm Copper. The table below lists RTD resistance vs. temperature.
