9.1.5.2 Analogueinputs
Properties
8Analogueinputs.Resolution14bitDifferentialinputs.Impedance0.8ΜW.
Apotentialdifferencetotallingupto100Vispermittedbetweenthedifferential
inputs('-'connector).Inputprotectionto±250V.
Sampling frequency
Realsynchronous/parallelsampling.
l Batchsampling:Amax.samplingfrequencyof20480Hzfor8channels.This
givesatotalsamplingrateofapprox.160000measurementvalues/s.
l Continuoussampling:Amax.samplingfrequencyof1024/2048/4096Hz
for8/4/2channels.Thisgivesatotalsamplingrateofapprox.8000meas-
urementvalues/s.
Signal bandwidth / Anti-aliasing filter (HW)
SignalbandwidthisDCto8kHz±0.8kHz.
Transfer rate for measurement data
Max.10000measurementvalues/s.
Measurement ranges
Sevenvoltagemeasurementrangesareavailable:
Measurementrange V ±10 ±5 ±2.5 ±1.25 ±0.625 ±0.312 ±0.156
Resolution mV 1.2 0.6 0.3 0.15 0.08 0.04 0.02
0/4…20mAsignalscanbeconvertedtovoltagesignalsusingterminatingres-
istorsof,forexample,50/100/250Ω.Resistorsaretobeexternallyattached
betweenthe'+'and'-'connectors.
Precision
DCprecisionisfactorysetusingcalibrationandadjustment.Basicprecisionis
±0.1to±0.4%ofthe(unipolar)measurementrange.
Measurementrange V ±10 ±5 ±2.5 ±1.25 ±0.625 ±0.312 ±0.156
DCprecision
mV ±10 ±5 ±2.5 ±1.3 ±1.3 ±0.9 ±0.6
% 0.1 0.1 0.1 0.1 0.2 0.3 0.4
For0/4to20mAsignals,terminatingresistorsneedtobeusedthathaveanaccur-
acygreaterthan0.1%.
