ISOLATED ANALOGUE OUTPUT
Isolation 500Vdc/peak ac Output User selectable 0-10V, 0-20mA or 4-20mA Scaling User selectable (e.g. 4 to 20mA = 3.0 to 5.0mm) Accuracy Better than 0.2% Temperature drift <100ppm / ºC Response 63% within 32mS, 99% within 100mS Resolution 0.05% (5mV or 0.01mA) Maximum voltage output 11V @ 22mA Maximum current output 22mA @ 18V Maximum load 900 Ω Output
damping filter Programmable
FAST-CAL CALIBRATION
Automatically calibrates and matches the indicator to a connected LVDT
transducer. TheDML300 reads the transducer's output at any two sensor positions. The two measured values
are stored as the calibration parameters. Calibration can be performed at any time.
