Note.
The
Analog I/P
tab is displayed only if
Source ID
for the Recording Channel is set to an analog
signal source – see Section 7.9.1, page 86.
If an analog input is assigned to more than one recording channel, changes to any of its
parameters and tags are applied to each channel the input is assigned to.
If an analog input is already assigned to another channel, the edit keys (
) are not available.

Input type
*
Select the electrical characteristics of the input.
Type
Select the input type required.
Note.
Simulated input types are available for evaluating recorder features
without the need for process connections.
If
Volt-free Digital Input
or
24V Digital Input
is selected, the input

sampled.
Note.
For thermocouple applications using an external fixed cold
junction, set
Type
to
millivolts
and select the appropriate linearizer type.
Linearizer units
Note.
This parameter is displayed only if a temperature linearizer type
(Thermocouple or RTD) is selected.
Select the linearizer units used to condition the input signal before it is
sampled.
*
If this parameter is changed to or from
Volt-free Digital Input
or
24V Digital Input
, internally-recorded data
files are recreated and unarchived data is lost.
