IO4—3 x PT100 RTD Thermistor Input Option Card

Description

IO board has 3 PT100 RTD inputs for motor thermal
monitoring. The inputs are designed to sense temperature
from –30 °C to +200 °C, warning for PT100 sensor open or
short. These sensors are used to fault the drive at a user set
temperature level.
