DMS-EB-TCJ/TCK www.murata-ps.com Thermocouple Input Application Boards for DMS-30PC/LCD Meters PRODUCT OVERVIEW FEATURES LDisplays –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 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 DMS-EB-HTB. SIMPLIFIED SCHEMATIC Figure 1.
