Thermocouple B, E, J, K, N, R, S, T or
–80 to 80 mV. (Set separately for each of
four inputs.)
The input range can be set within any of
the measurable input ranges shown in
Table 1 (below).
Note Internally, inputs are processed in
five ranges (refer to Table 2 below),
so accuracy and resolution accord
with these internal ranges.
Data to be stored in the allocated words in
the CIO area must be scaled (with the
minimum and maximum values set). Data
can be stored at 0% to 100%.
The value derived from carrying out the following processing in order of the actual pro-
cess data in the input range is stored in four digits hexadecimal (binary values) in the
allocated words in the CIO Area.
1) Mean value processing → 2) Scaling → 3) Zero/span adjustment → 4) Output limits
±0.1% (of internal range full span)
As shown in the following equation, the accuracy depends on the ratio of the selected
internal range (0 to 4) span to the set input range span.
Accuracy = ±0.1% x
±0.015% /°C, for any of internal range numbers 0 to 4.
1/4096 (of internal range full span)
As shown in the following equation, the resolution depends on the ratio of the selected
internal range (0 to 4) span to the set input range span.

Specifications
Sensor type, input range, and scaling to
industrial units are separate for each of
the 4 inputs.
Note Sensor type, input range, and scal-
ing to industrial units are set in the
DM Area.
Example:
Thermocouple: K; input range: 0 to
500°C; industrial unit scaling: 0 to 500°C.
DM Area settings are as follows:
Thermocouple: 3 (0003 Hex)
Input signal maximum: 5000 (1388 Hex)
Input signal minimum: 0 (0000 Hex)
Industrial unit maximum value stored: 500
(01F4 Hex)
Industrial unit minimum value stored:
0 (0000 Hex)
