4WPB100 and 4WPB1K PRT Bridge
Terminal Input Modules
Terminal input modules connect directly to the datalogger’s input
terminals to provide completion resistors for resistive bridge
measurements, voltage dividers and precision current shunts. The
4WPB100 and 4WPB1K are used to provide completion resistors
for 4-wire half bridge measurements of 100
Ω
and 1k
Ω
Platinum
Resistance Thermometers (PRTs), respectively.

Figure 1 Terminal Input Module
If you have a silver CR10 Wiring Panel, you can use a maximum
of two Terminal Input Modules at a time. This is because only
differential channels 3 and 6 have a ground terminal next to the
low side of the differential channel. You may need to bend the
TIM leads slightly to fit the TIM into a silver wiring panel.
