Probe Wiring Diagrams
This section describes the wiring schema for connecting thermistors, RTD and sensors with reference to the most
frequently used configuration. If the distance between the probe and the drive is longer than 3 meters (9.84 feet) 4-wire
configuration is advisable.
PT-1000 or NI1000 2-wire connection:
•
where Rw is the resistance of the wire and Rt is the resistance of the probe. Use shielded cables to connect the
PT1000/NI1000 to the card and shortcut the shield to the metal cover of the drive (System Ground).
PT-1000 or NI1000 3-wire connection:
•
where Rw is the resistance of the wire and Rt is the resistance of the probe. Use two twisted pair shielded cables to
connect the PT-1000/NI-1000 to the card and shortcut the shield to the metal cover of the drive (System Ground).
