DAT2145 Din Rail Thermocouple converter.
Din Rail Thermocouple Converter DAT2145.
• Thermocouple Temperature Converter.
• DIP Switch Programmable.
• Voltage Linear.
General Description

The Din Rail Thermocouple converter DAT2145 is a DIN Rail mount temperature converter with DIP Switch programmability.
The DAT2145 will convert the thermocouple input and provide a 4-20mA, 0-20mA or 0-10 V output signal which is linear to the voltage input. The DAT2145 has internal cold junction compensation.
The DAT2145 is accurate to 0.1% full scale and has less than 0.02%/°f thermal drift.
It is possible to set the coarse range and zero with the DIP switches. Use the potentiometers to fine tune the output whilst keeping within the minimum and maximum ranges shown in the table on the data sheet. The potentiometers are located on top of the DAT2145.
The DAT2145 is in compliance with the standard 89/336/CEE on the Electromagnetic Compatibility.
The DAT2145 is housed in a plastic enclosure of 12.5 mm thickness suitable for DIN rail mounting in compliance with EN-50022 and EN-50035 standards.

How to calibrate a Thermocouple Converter

  1. Turn on the Thermocouple Converter and leave to warm up for 3 minutes.
  2. Calculate the span by subtracting the zero from the maximum range.
  3. Choose the correct DIP switch setting for the Span and Zero.
  4. Connect a calibrator to the input connections and a calibrated multimeter to the output connections.
  5. Set the calibrator to 10% of the span and adjust the output to 10% output with the zero potentiometer.
  6. Set the calibrator to 90% of the maximum range and adjust the output to 90% of full scale.
  7. Repeat step 4 and step 5 unit the output reads accurately.
