Measuring current approx. 200 µA with RTD
Types of measuring 2-, 3-, 4-wire connection
Lead resistance max. 50 Ω per line
Measuring circuit monitoring sensor breakage, sensor short-circuit
Thermocouples type B, E, J, K, N, R, S, T (IEC 584-1: 1995)
type L (DIN 43710: 1985)
type TXK, TXKH, TXA (P8.585-2001)
Cold junction compensation external and internal
Measuring circuit monitoring sensor breakage
Potentiometer 0 ... 20 kΩ (2-wire connection), 0.8 ... 20 kΩ (3-wire connection)
Voltage selectable within the range -100 ... 100 mV
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.
