Single-ended inputs
Starting from version 2.20.00 it is possible to double the number of analogue inputs, passing from 8
to 16. This function is available only for sensors with tension or current signals (this function is
called s
ingle-ended
). Resistive signals, instead, go on occupying a full single physical input (this
function is called
differential
).
Differential inputs are best immune from electromagnetic disturbances than single-ended ones and,
when possible, they have to be preferred.
All sensors generating tension or current signals, with or without external power, can be connected
to single-ended inputs (see connection scheme).
Sensors with analogue signal (single-ended mode):
The drop resistance, indicated by Rx, is used to return a voltage signal from the current generated
by the sensor. Program
3DOM
supplies a library for the setting of the LSI LASTEM sensors,
including some powered outputs; for such models the settings have been arranged to use the
energized scale -300÷1200 mV, thus being able to use 50
Ω
drop resistances
.
When a probe is added using the 3DOM probes library, those sensors are always added in
differential mode; for this reason is not possible add a single-ended probe to a configuration where
