1. Overview
This chapter presents the information how to use this manual and operate the module
if you are already familiar with Microsoft Visual Studio and C# programming language.
Introduction
JYTEK PCIe/PXIe-6301 is a high-resolution and high-speed temperature measurement
module designed for PT100 Resistance Temperature Detector (RTD).
PCIe/PXIe-6301 supports two wiring topologies, “4-wire mode” and “3-wire mode”,
which can be selected by software.
“4-wire mode”: each channel can support 2-wire, 3-wire or 4-wire RTD configuration
and the module provides 20 channels of analog temperature measurements.
“3-wire mode”: each channel can support 2-wire or 3-wire RTD configuration and the
module provides 32 channels of analog temperature measurements.
PCIe/PXIe-6301 can measure resistance up to 400 Ωto cover the full range of PT100
RTD measurements and the maximum sampling rate is up to 800 samples per second.
The PCIe/PXIe-6301 supports digital and software trigger. All trigger signals are routed
through PFI or PXI chassis backplane.
PCIe/PXIe-6301 module channel grouping is shown in Table 1.

Figure 1 JYPEDIA Information
In a Learn by Example section, the sample program is in bold style such as Winform
AI Continuous MultiChannel; the property name in the sample program is also in bold
style such as SamplesToAcquire; the technical names used in the manual is in italic
style such as SampleRate. You can easily relate the property names in the example
program with the manual documentation.
In a Learn by Example section, the experiment is set up as follow. A PCIe/PXIe-6301
card is plugged in a desktop computer. The PCIe/PXIe-6301 is connected to a TB- 68
terminal block. A signal source is also connected to the same terminal block as shown
in Figure 2.

2. Hardware
The JYTEK 6301 series are one of the family of temperature measurement module,
which can run on PCIe, PXIe, TXI (Thuderbolt) and USB buses (coming soon). JYTEK
6301 series on different buses are shown in Table 2.
Table 2 6301 on different buses
Sensor Connection
PCIe/PXIe-6301 can support 2-wire, 3-wire or 4-wire RTD connection at the same time.
The wiring configuration used by each channel can be independently configured by
software.
2-wire RTD connection
When using a 2-wire RTD configuration, user needs to connect the negative terminal
of current excitation (Ex-) to the AI- terminal as shown in Figure 3. Due to the presence
of lead wires resistance, this type of connection may introduce large measurement
errors, which are related to the material of the lead wire. This type of wiring is not
suitable for high precision temperature measurement needs.
