XW-EDA Wiring
The XW-EDA model supports thermocouples, RTD's, and precision process inputs. The sensor inputs signals are provided on
an M12, 4-pin female connector and are logically broken into 2 unique channels.
Thermocouple
The Thermocouple Input interface provides interfaces to type J, K, T, E, N, R, S, B and C thermocouples with the capability of
enabling or disabling the open detect feature.
To use these features, change the input type to Single TC or Dual TC using SYNC.
Cold Junction Compensation
The thermocouple input interface offers cold junction compensation calibration. To achieve proper Ice Point calibration,
you must be able to immerse your thermocouple into an environment that is stabilized at 0°C (32°F).
To use this calibration feature, change the input type to Single TC or Dual TC using SYNC (see Figure 30) and click
Calibration beneath the input interface. Once the Thermocouple is stable in the 0°C environment, click calibrate.
