7.8.2 Analog Input Configuration

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 7.8.1, page 93.

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 (
•1 If this parameter is changed to or from 'Volt free digital input', internally recorded data files are
recreated and unarchived data is lost.

•1
Select the electrical characteristics of the input.
Note.

Simulated input types are available for evaluating recorder features
without the need for process connections.

If 'Volt free digital input' is selected, the input channel becomes a
digital input channel – see Section 7.8.3, page 99.

Select 'Off' to disable an analog input.
Warning. Ensure that the appropriate electrical connections have been
made – see Section 2.3, page 14.
Select the linearizer type and the units used to condition the input signal
before it is sampled.
Note.

For thermocouple applications using an external fixed cold junction,
set 'Type' to 'millivolts' and select the appropriate linearizer type.

Linearizer units are displayed only if a temperature linearizer type
(Thermocouple or RTD) is selected.
Set the required electrical range.
Note.

Applicable only to mA, mV, V and Resistance input types.

The range of the electrical input signal is determined by the input
type – see Table 7.3:
