Resistor Connections
A package of four 10 M
Ω
resistor networks is included in the TBX-1303
kit. You can install these resistor networks as RP5, RP6, RP7, and RP8.
Refer to Figure 4 for placement. With this configuration, thermocouples are
either ground-referenced or floating.
Table 3 shows the relationship between the channel input signals and the
resistor networks.
