Output

Connection sidecontrol side

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.
