Introduction
This chapter describes the basic features of the PowerDAQ™
Thermocouple Rack (TCR).
About the PowerDAQ™ TCR
Thank you for purchasing a PowerDAQ™ TCR. The PowerDAQ™
TCR board was designed to work with your PowerDAQ OCI data
acquisition board.
The PowerDAQ Thermocouple Rack contains sixteen isolated
inputs for J or K type thermocouples. It converts the thermocouple
inputs to a voltage, and then it is fed as an input to a PowerDAQ
PCI board, with an input range of 0-10V.
The PD-TCR is based on a complete instrumentation amplifier and
includes a thermocouple cold junction compensator for each
channel. It combines an ice point reference with a precalibrated
amplifier to produce a high level (10 mV/C) output directly from a
thermocouple signal.
Each PD-TCR channel is precalibrated by laser wafer trimming to
match the characteristic of type J or K inputs.
Chapter 1: Introduction
The temperature transducer voltages (ZERO potentiometer) and
gain control (GAIN potentiometer) can be used to recalibrate the
PD-TCR in the field.
The PD-TCR channel accuracy for both the J and K type is ±1% is
a working temperature environment of 0°C to +50°C.
Features
The major features of the PowerDAQ™ TCR are:
• Each channel provides cold junction compensation
• Zero, and scale factor are all pre-calibrated by laser wafer
trimming
• Calibrate ZERO and gain for each channel
• Differential input rejects common-mode noise voltage on the
thermocouple leads
• Includes PowerDAQ SDK
PowerDAQ PCI Board User Manual 2
Chapter 1: Introduction
• Data logging and display software with source code in Delphi
• LabVIEW for Windows VI's
• DASYLab, HP VEE and TestPoint support
• Up to 4 PD-TCR's can connect into one or more PowerDAQ 64
channel boards
• Up to 64 Non multiplexed inputs per system
• Uses PowerDAQ PCI bus DAQ boards
• Multiple PowerDAQ boards can be plugged into one PC. Only
limited by PCI slots
• Can be mounted in 19" rack using PD-19RACKW
• Each PD-TCR-16-x requires an external universal power
supply (PD-PSU-5/15)
Note
For the full list of specifications, see Appendix A:

Installation and Configuration
This chapter describes the hardware and software installation and
configuration of the PowerDAQ™ TCR.
Unpacking
Your PowerDAQ™ TCR is wrapped in an antistatic bag to protect
against electrostatic charges that might damage the board. To avoid
damage, proceed as follows:
1. Ground yourself with a grounded wrist strap or grounded
source.
2. Discharge the static electricity by taking the board in the
antistatic bag and touching the metal part of your PC.
3. Remove the board from the antistatic bag. We suggest you
save the bag.
4. Inspect the board for any damage. If any damage is found,
notify your distributor to return the board to the manufacturer.
See Appendix B: Common Questions and Support.
Note
The PowerDAQ™ TCR contain sensitive electronic
components. Please make sure the proper grounding and
electrostatic conditions are used.
Hardware
You can install your PowerDAQ™ TCR as a stand-alone unit or in
a 19" rack. We recommend you use the following instructions:
1. Turn the PC Off.
2. Refer to your PowerDAQ PCI board hardware manual for
DAQ board installation instructions.
3. The PD-TCR requires external power to be wired at the J3
EXT POWER connector. (The manufacturer suggests using
the PD-PSU-5/15 power supply unit. This PSU is switchable
110/220V and can support up to 4 PD-TCR's).
