CHARACTERISTICS AND CONNECTIONS

ANALOG INPUTS
DigiRail Connect
has versions with 2 channels of analog inputs, identified as
A1
and
A2
, on its front panel. These channels are available only on
RAMIX models and are suitable for measuring temperature or any other values represented by standard linear electrical signals.
Each channel can be configured through the
NXperience
configurator software (see the
chapter).

The possible input types, along with their respective measuring ranges, are listed in
Table 02
.

Table 02
– Input types and sensor measurement ranges
Analog channels
A1
and
A2
are not electrically isolated from analog output channels
O1
and
O2
, but are electrically isolated from other
DigiRail
Connect
channels.
For the
Temperature Sensors
group, the temperature unit setting is required. For the
Linear Analog Signals
group, the measurement range
definition is required.
For all types of input signals, it is necessary to set values for the operating parameters of the
DigiRail Connect
analog input channels (see
chapter):
•
Sampling Rate:
Allows you to set the number of readings performed each second by the analog input channel on the received input signal: 1
reading per second or 10 readings per second.
•
Filter:
Allows you to set the
Time Constant
value of a filter to be applied over the measured input signal. Parameter used to improve the
stability of the measured signal. Adjustable between 0 and 1200 seconds.
