Thermocouple Wire Installation
There are five different types of thermocouple probes that are supported by the 920i . Table 1 lists the various
thermocouple probe types, their corresponding wire colors, and their temperature ranges.
Use the following instructions to connect thermocouple cables in indicators.
1. Insert the multi-cable bushing (PN 73997), into one of the available cord grips on the 920i located closest to
the analog input option (See Figure 6 on page 3.).
Figure 4 Multi-Cable Bushing
2. Route the thermocouple wire through one of the holes in the multi-cable bushing (Figure 4).
3. Strip 1/4-inch of insulation from the end of the thermocouple cable.
4. Install wires into the J3 connector on the analog input option card as shown in Table 2 on page 3. Depending
upon the type of cable used, the wire colors will differ however, the – signal will always be red wire. See
Figure 6 on page 3.
