Thermocouple Input Application Boards for DMS-30PC/LCD Meters
LDisplays –50 to +200°C range
Interfaces with type J or K type thermocouples
Typical accuracies as low as ±1.5°C
Use with:
Description: The DMS-EB-TCJ and DMS-EB-TCK Application Boards interface type J or K thermocouples to Murata Power Solutions' 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 temperatures across the board and
keep temperature-gradient induced errors to a minimum.
Accuracy: As the accuracy specifications indicate,
the DMS-EB-TCJ and TCK boards are for generalpurpose 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
