Analog Input Configuration Page
Input to Configure
Select the analog input to configure (A1 to A6). On entry the default is
NONE
.
Input Type
Select the analog input type required:
RTD
–
Resistance Thermometer
TC
–
Thermocouple*
R
–
Resistance
V
–
Voltage
mA
–
Low current (set to at least one decimal point)
mV
–
Low voltage
OFF
–
Sets input to off (analog I/P A1 cannot be turned off)
* For thermocouple applications using an external fixed cold junction, select
mV
input type.
Note. Before selecting input types other than
TC
and
mV
, ensure links
are set correctly – see Section 4.5.7.

Input Electrical Range
Defines the electrical range (mA, mV, V or
Ω
) over which the input operates.
The limits are as specified in Table 3.1 on page 19.
The values and the decimal point position should be set such that the input is
calculated to the maximum number of decimal places.
