Application Boards for
DMS-30PC/LCD Meters
Features
Technical Notes
• Displays –50 to +200°C range
• Interfaces with type J or K
type thermocouples
• Typical accuracies as low as ±1.5°C
• Use with:
DMS-30PC-1-RL
DMS-30LCD-1-5
Description: The DMS-EB-TCJ and DMS-EB-TCK Application Boards interface type J or K
thermocouples to DATEL's low-power, ±2V input, DMS-30PC-1-RL or DMS-30LCD-1-5 digital
voltmeters. These low-cost add-on boards provide a quick easy method of displaying
temperature (in degrees Celsius only) within a –50 to +200°C range.
Installation: A screw-type terminal block (TB1) accepts direct thermocouple inputs and
provides quick connection for the +5V power supply. All necessary I/O connections for the
meter — including activation of the correct decimal point — are built-in. Simply solder the
board to the meter, connect the appropriate thermocouple, and the installation is complete.
Using low-power meters, with either LCD or LED displays, will maintain uniform tempera-

tures across the board and keep temperature-gradient induced errors to a minimum.
Accuracy: As the accuracy specifica-
tions indicate, the DMS-EB-TCJ and TCK
boards are for general-purpose
temperature monitoring over the range of
–50 to +200°C. However, fairly high
accuracy can be obtained with K
thermocouples from 0 to +200°C. For
higher accuracy temperature readings,
see the DMS-EB-HTB.
