2.5 ANALOG INPUT
. Number of analog inputs: Two, high voltage and low voltage, isolated between them..
2.5.1 High voltage analog input
. 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.
. Analog input measurement resolution: 16 bit.
. Analog input measurement accuracy: 0.5% of the reading ± 0.1% of the selected range, for DC
inputs: 1 % of the reading ± 0.2% of the selected range, for AC inputs.
. Analog input impedance: more than 200 kOhm.
. Analog input measurement sampling rate: 20 kHz max.
. Connection: via two safety sockets for the input, plus two safety sockets for the polarizing voltage.
2.5.2 Low voltage analog input
. Input voltage range: ± 5 V.
. Analog input measurement resolution: 16 bit.
. Analog input measurement accuracy: 0.5% of the reading ± 0.1% of the selected range.
. Analog input impedance: more than 200 kOhm.
. Analog input measurement sampling rate: 20 kHz max.
. Availability of a polarizing voltage to supply linear position transducers. Voltage value: - 5 V;
maximum output current 5 mA; minimum transducer resistance 1 kOhm. The output is isolated
from other circuits.
. When the input is used with a position transducer, the software allows displaying: positions,
strokes, speed (datum point). These measurements are defined by the position of the cursors. In this
instance, it is possible to input the transducer stroke, and to set the unit of measurement as
millimeters, degrees or inches.
. Connection: via a shielded connector for the input, and two safety sockets for the polarizing
voltage.
2.6 TIME MEASUREMENT TRIGGERS
The following time measurement trigger options are user selectable:
. Internal: the time measurement starts as the first Open or Close coil command is issued by the
driving circuit.
