accuracy
The following are exceptions.
K, T, or N below −100°C
U, L, or PL2
R or S below 200°C
B below 400°C
W
The indication accuracy applies under the following conditions.
• The standard mounting direction must be used (i.e., mounting 1).
• The terminal block and main block must have the same serial
number.
• The Units on both sides of and directly next to the GRT1-TS2T
must be in the following list of Units supporting an indication accu-
racy of ±2°C ±1 digit max.
Conversion 250 ms/2 points
cycle
Temperature Binary data two's complement (Four-digit hexadecimal when nor-
conversion data mal display mode is selected or 8-digit hexadecimal when 1/100
display mode is selected.)
Isolation method Between input and communications lines: Photocoupler isolation
Between temperature input signals: Photocoupler isolation
The indication accuracy depends on the mounting direction and the Units on
both sides of and directly next to the GRT1-TS2T. Refer to the following infor-
mation.
■ Indication Accuracy Dependence on Mounting Direction and Mounted
Units
The indication accuracy depends on the direction in which the Temperature
Input Unit is mounted and on the Units mounted on both sides and directly
next to the GRT1-TS2T. The following indication accuracy applies if the stan-
dard mounting direction (i.e., mounting 1) is not used or if the Units mounted
are not on the list of Units supporting an indication accuracy of ± 2 ° C ± 1 digit
max.
± 4 ° C ± 1 digit max.
The following are exceptions.
Input type
K, T, or N below −100°C
U, L, or PL2
R or S below 200°C
B below 400°C
