General Description

The DAT8016 is an 4 Channel fully isolated 0-10 V dc to Modbus TCP converter using Ethernet Base 10/100T Communication. The DAT8016 can accept other voltage ranges such as -10 to +10 Vdc, 2-10 Vdc. The inputs, Ethernet and power supply are isolated from each other up to 1500VAC for 1 minute. The DAT8016 accepts a wide tolerance on it's power supply from 10 to 30 Vdc and it is mounted on DIN Rail.

Application Note Modbus TCP Thermocouple input module DAT8016..
Printed Version

Set Up the DAT8016.

  1. Connect 24 Vdc to O and P.
  2. Connect CAT5 crossover cable to PC and Ethernet RJ45 Port on the DAT8016.
  3. Connect a Calibrator or short the input to 1 and 2.
  4. Power up the DAT8016 Modbus TCP Thermocouple Module.

It is extremely important to use a Cat 5 Crossover cable unless a router is used.

How to read the Analog Input Signal.

  1. Click the Analog Input at the bottom of the page.
  2. Select the type of input being measured.
  3. Select Tc K for K type thermocouple.
  4. Click Save to save to the DAT8016.
  5. Click Read to measure the Input.
  6. Adjust the calibrator to check the range.
The input selection can be seen below.
  • 250mV.
  • J type thermocouples.
  • K type thermocouples.
  • R type thermocouples.
  • S type thermocouples.
  • T type thermocouples.
  • B type thermocouples.
  • E type thermocouples.
  • N type thermocouples.
Each input can be different and they are all isolated from each other. The red indication under Break means the input is open circuit. By clicking the “Set Same Input” button you enable all the inputs to be the same as Analog Input 0.
