Features
- Provides completion resistors for 100 ohm and 1 kohm platinum resistance thermometer (PRT) measurements
General Description
Terminal input modules (TIMs) are small peripherals that provide completion resistors for resistive bridge measurements, and act as voltage dividers and precision current shunts. The modules attach directly to the datalogger's input terminals.* Each module provides circuitry to connect one sensor, except for the voltage dividers which allow connection of two single-ended sensors.The 4WPB100, 4WPB1K Terminal Input Modules are designed to provide completion resistors for 100 Ohm and 1 kOhm Platinum Resistive Thermometer (PRT) measurements. The PRT's resistance should match the module's resistance.
* Note: Limited compatibility with silver CR10 wiring panel.
