More Information

Overview Manuals Sensor Setup Diagnostics Filtering Application
  • Accepts two J, K, N, S, B, or R thermocouple channels
  • Includes integrated terminal-temperature compensation and direct raw-value measurement
  • Provides configurable filtering, selectable resolution, and explicit diagnostic values

X20AT2402 is a B&R thermocouple input module designed for the X20 System.

The module converts thermocouple or raw millivolt signals into X20 controller values while reporting range, open-circuit, and general-fault conditions.

Before installation or replacement, verify the complete material number, sensor type, the hardware-revision condition for type N, thermocouple polarity, terminal-temperature conditions, filter and resolution settings, X20TB06 or X20TB12, a compatible bus module, and project scaling.

Availability, condition, price, and shipping time for X20AT2402 are confirmed during quotation.

  • The configured sensor type must match the connected thermocouple alloy
  • Type N measurement requires hardware revision D0 or later
  • Polarity and terminal-temperature conditions affect measurement validity
  • Open inputs are reported with the documented 0x7FFF value
  • Range undershoot, overshoot, and general faults use distinct status values
  • Channel and module indicators support commissioning and fault localization
  • Filter time is configurable between 1 and 66.7 milliseconds
  • Resolution can be selected between 0.1 and 0.01 degree Celsius
  • Conversion timing depends on enabled-channel count and filter configuration
  • Two-channel thermocouple temperature acquisition in X20 control stations
  • Temperature-control systems using J, K, N, S, B, or R sensors
  • Direct low-level millivolt measurement in distributed I/O systems
Description
X20AT2402 is a B&R thermocouple input module for the X20 System automation platform.

It acquires two thermocouple channels with 16-bit sigma-delta conversion, configurable filter time and resolution, direct raw-value measurement, and integrated terminal-temperature compensation.

Before installation or replacement, confirm the complete material number, sensor type, the hardware-revision condition for type N, thermocouple polarity, terminal-temperature conditions, filter and resolution settings, X20TB06 or X20TB12, a compatible bus module, and project scaling.

Technical notes
X20AT2402 supports two thermocouple channels, but type N requires hardware revision D0 or later; verify sensor alloy, polarity, compensation conditions, filter and resolution settings, terminal block, bus module, and saved Automation Studio configuration.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How should the correct thermocouple type be selected on B&R X20AT2402?
Match the Automation Studio channel setting to the actual sensor alloy, then verify polarity, compensation conditions, wiring, and engineering-unit scaling before commissioning.
Why must the hardware revision be checked before using type N with B&R X20AT2402?
B&R specifies type N operation only for hardware revision D0 or later, so identify the installed hardware before assigning a type N sensor.
What should be investigated when B&R X20AT2402 reports 0x7FFF?
Check for an open thermocouple, loose terminal, broken extension lead, incorrect terminal mapping, or an actual range overshoot before treating the value as a valid temperature.
How can unstable measurements on B&R X20AT2402 be reduced?
Inspect sensor polarity, thermocouple-compatible cable, shielding, ground potential, airflow around the compensation point, and the selected filter time.
Can B&R X20AT2402 use either a 6-pin or 12-pin terminal block?
Yes. B&R documents X20TB06 and X20TB12; preserve the approved terminal assignment and do not assume that the terminal block is supplied with the electronic module.
What affects the response time of B&R X20AT2402?
Enabled-channel count and filter configuration affect conversion timing, so select settings that balance noise rejection with the required process response.
What information should be saved before replacing B&R X20AT2402?
Record sensor type, hardware revision, polarity, resolution, filter time, raw-value use, diagnostic handling, terminal mapping, bus module, and Automation Studio configuration.
