Note 1 (Table 1):
Accuracy is ±0.1% of the full-scale span, typical, or per narrow span
specification, whichever is greater.
Note 2 (Table 1):
Accuracy is given with CJC switched off. CJC inaccuracy must be
added to the inaccuracy numbers in Table 1 to determine potential overall inaccuracy.
Relative inaccuracy with CJC enabled may increase by as much as
0.5
C during warm-
up period but will be
0.2
C typical after five minutes.
TC Input Reference Test Conditions:
TC Type J with a 10mV
minimum span (e.g. Type J with 200
C span); Ambient = 25
C; Power
Supply = 24VDC; R-
load = 250Ω.
TC Break Detection
: Can be selected for Upscale or Downscale open
sensor or lead break detection. Break detent selection cannot be
disabled.
TC Input Bias Current
: ±250nA typical (TC break).

Input Gain:
PGA gain is internally adjustable for 1, 2, 4, 8, 16, 32, 64,
128, 256, and 512 mV/mV.
Note:
Cold Junction Compensation may be switched off to permit the
direct connection of an mV source to the input for ease of calibration.
For best results, allow the module to warm up for 15 minutes prior to
calibrating CJC.
TC Linearization:
Within
0.25
C of the NIST tables.
DC Voltage (See Table 2):
Can be configured for the bipolar DC voltage
range of
100mVDC.
Voltage Input Reference Test Conditions:
±100mV range with a
10mV minimum calibrated span; Ambient = 25
C; Power Supply =
24VDC; R-
load = 250Ω.
General Analog Specification:
Input bias current:
250nA typical.
Voltage Input Reference Test Conditions:
100mV input range with
10mV span; Ambient Temperature = 25
C.
Input Over-Voltage Protection:
Bipolar Transient Voltage
Suppressers (TVS), 5.6V clamp level typical.
Input Filter Bandwidth:
-3dB at 57Hz, typical, normal mode filter.
Input Response Time:
Output completes transition in less than 8 milli-
seconds, typical.
Accuracy:
TC accuracy is listed in Table 1. CJC accuracy is
0.5
C
(See Table 2). Voltage accuracy is better than
0.05% of span.
This includes the effects of repeatability, terminal point conformity,
and linearization, but does not include sensor error.
Measurement Temperature Drift:
Better than
75ppm/
C
(±0.0075%/
C).
Analog to Digital Converter (A/D):
A
24-bit
-
converter.
