- Accepts six 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 fault values
X20AT6402 is a B&R thermocouple input module designed for X20 System I/O stations.
The module converts thermocouple or raw millivolt signals into controller values while monitoring range, open-circuit, and general-fault conditions.
Before installation or replacement, verify the complete material number, sensor type, the revision condition for type N, thermocouple polarity, cold-junction conditions, filter and resolution settings, X20TB12, X20BM11 or X20BM15, and project scaling.
Availability, condition, price, and shipping time for X20AT6402 are confirmed during quotation.

- Sensor type is configured to match the connected thermocouple alloy
- Type N measurement is supported only on hardware revision D0 or later
- Thermocouple polarity and terminal-temperature conditions affect valid measurements
- An open input is reported with the documented 0x7FFF value
- Range undershoot, range overshoot, and general faults use distinct digital 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 time changes with enabled-channel count and the selected 50 hertz filter behavior
- Multi-channel thermocouple temperature acquisition in X20 control stations
- High-temperature process monitoring using J, K, N, S, B, or R sensors
- Direct low-level millivolt measurement in distributed I/O systems
