NALOG INPUT
Number of analog inputs: ten in all, programmable. Common characteristics of analog inputs:
. Measurement resolution: 16 bit.
. Measurement accuracy: 0.5% of the reading ± 0.1% of the selected range.
. Impedance: more than 200 kOhm.
. Measurement sampling rate: 20 kHz max.
2.5.1 Coil currents
The two coil current measurements; optionally four, above described are included in the total of ten
analog channels.
2.5.2 High voltage analog inputs
. Number: two, with no common point.
. Input voltage ranges: ± 5 V; ± 50 V; ± 500 V DC (3.5; 35; 350 V AC), user selected. These ranges
allow measuring all AC and DC voltages.
. Connection: via four safety sockets.
2.5.3 Low voltage analog inputs
. Number: three plus one.
. For all of them, the input voltage range is ± 10 V.
. Three of them are for transducers measurements or for analog input measurements, and have the
same reference point; the fourth one is dedicated to the micro-Ohmmeter.
. For the three inputs, they can be used for position or pressure transducers, or for analog signal
measurements.
