Çıkış

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.
