SKF Multilog On-line System IMx-16Plus
User Manual
Revision Letter A
SKF provide 250-ohm load resistors for this purpose and double deck connectors to
facilitate the installation. These SKF provided resistors must be used and are colour-
coded blue, refer
Figure 11

Note: All ground terminals (G1
–
G16) of the analogue inputs are connected to each
other, to secure a common ground level. As all channels are referenced to
chassis/enclosure ground, take care to avoid ground loops!
2.5.10 Connecting PT1000 sensors (A9 to A16)
The SKF Multilog IMx-16Plus supports 2-wire PT1000 temperature sensors on the
last 8 channels (A9 to A16). They should be connected as shown in
Figure 12

Note, that the PT1000 sensor lead wires (red and white) are not polarity sensitive
and can have reversed connections to the IMx-16Plus, without any impact on the
measurement function.
Also, note that the IMx-16Plus provides the required sense current for the
measurement and that this is enabled by @ptitude Observer software, automatically
when sensor type PT1000 (C or F) is selected.
