type TXK, TXKH, TXA (P8.585-2001)
  Cold junction compensation external and internal
  Measuring circuit monitoring sensor breakage
Voltage selectable within the range -100 ... 100 mV
Potentiometer 0 ... 20 kΩ (2-wire connection), 0.8 ... 20 kΩ (3-wire connection)
Input resistance ≥ 1 MΩ (-100 ... 100 mV)
Output
Connection output I: terminal 7: source (-), sink (+), terminal 8: source (+), terminal 9: sink(-)
Output Analog current output
  Current range 0 ... 20 mA or 4 ... 20 mA
  Fault signal downscale 0 or 2 mA, upscale 21.5 mA (acc. NAMUR NE43)
  Source load 0 ... 550 Ω 
open-circuit voltage ≤ 18 V
  Sink Voltage across terminals 5 ... 30 V. If the current is supplied from a source > 16.5 V,
series resistance of ≥ (V - 16.5)/0.0215 Ω is needed, where V is the source voltage.
The maximum value of the resistance is (V - 5)/0.0215 Ω.
