Address Range: 0-15 (1-15
are for multidrop loops)
Transmission Speed:
1200 baud
Character Format:

Input Accuracy: Refer to
Table 1 (page 3)
Analog Output Accuracy:
±0.015% of span
Overall Accuracy: The
overall accuracy of the unit is
the combined input and
output accuracy. It includes
the combined effects of
linearity, hysteresis,
repeatability, and adjustment
resolution. It does not
include ambient temperature
effect. For T/C input only,
add the Reference Junction
