Thermocouple Reference: Accurate to better than 0.4C
typical at 25C. Ambient temperature effect of the CJC is
0.01C/C typical. Note: The software configuration
program will allow the CJC to be switched off to allow direct
connection of a mV source to the input.
TC Linearization: Within 0.25C of the NIST tables.

DC Voltage (See Table 6): User-configured for the bipolar DC
voltage ranges shown in Table 6.
Voltage Input Reference Test Conditions: 15.6mV input
range with 10mV span; Ambient Temperature = 25  C; Power
Supply = 24V DC; Alarm Delay = 200ms.
Input bias current: 25nA typical.
General Input Specifications
Accuracy: RTD accuracy is listed in Table 4 and TC
accuracy in Table 5. Voltage accuracy is better than
0.05% of span. This assumes that module was
calibrated warm. Includes the effects of repeatability,
terminal point conformity, reference junction error (TC
inputs), and linearization, but does not include sensor
error. Accuracy noted does not include analog output
accuracy.
Resolution: Given in Table 6 below per applicable range.
Ambient Temperature Effect: Better than ±0.005% of input
span per C, or 1.0uV/C, whichever is greater.
Response Time: 200ms typical, for an analog output to
reach 98% of the final value for a step, with input
averaging set to "1" This time will increase as the input
averaging number increases. See Relay Response Time
for alarm output response.
Input Filter Bandwidth: -3dB at 3Hz, typical.
Noise Rejection (Normal Mode): 40dB @ 60Hz, typical
with 100 input unbalance.
Noise Rejection (Common Mode): 140dB @ 60Hz, typical
with 100 input unbalance.
Analog to Digital Converter (A/D): A 16-bit - converter.
Input Conversion Rate: 5 conversions per second.
Input Filter: Normal mode filtering, plus digital filtering
optimized and fixed per input range within the - ADC.

ANALOG OUTPUT SPECIFICATIONS

These units contain an optically isolated DAC (Digital-to-
Analog Converter) that provides a process current or voltage
output. Calibration can only occur with respect to one of the
outputs, voltage or current, and only one of the outputs may
operate at a time.
Note: For sensitive applications, high frequency noise may be
reduced by placing a 0.1uF capacitor directly across the load.
Voltage Output Specifications:
Output Range: 0-10V DC, 0-5V DC.
Output Accuracy: See Table 7.
Output Current: 0-10mA DC maximum.
Output Impedance: 1.
Output Resolution: See Table 7.
Output Short Circuit Protection: Included
Current Output Specifications:
Output Ranges: 0-20mA DC, 4-20mA DC, or 0-1mA DC.
Output Maximum Current: 21.6mA typical.
Output Accuracy: See Table 7.
Output Compliance: 10V Minimum, 12V Typical.
Output Resolution: See Table 7.
Output Load Resistance Range: 0 to 550, typical.

Notes (Table 7):
1. Voltage outputs unloaded. Loading will add "I*R" error.
2. Software calibration produces high accuracy.
3. All current and voltage ranges are subsets of the 0-24mA
range which provides under and over range capability.
