Voltageselectable within the range -100 ... 100 mV
Input resistance≥ 1 MΩ (-100 ... 100 mV)
Connectionoutput I: terminal 7: source (-), sink (+), terminal 8: source (+), terminal 9: sink(-)
OutputAnalog current output
Current range0 ... 20 mA or 4 ... 20 mA
Fault signaldownscale 0 or 2 mA, upscale 21.5 mA (acc. NAMUR NE43)
Sourceload 0 ... 550 Ω
open-circuit voltage ≤ 18 V
SinkVoltage 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.
