INPUT SPECIFICATIONS
The input type is factory-set to K thermocouple, and the
input range to 0 to 100°C.
EXPLANATIONS OF TERMS
■ ACCURACY
This transmitter’s accuracy is theoretically defined as the
addition of A/D and D/A conversion errors:
See Table 1 for the available input type, the minimum span,
and the maximum range.
■ DC mV & V
Accuracy = A/D Conversion Error + D/A Conversion Error
Input resistance: ≥ 1 MΩ
■ Thermocouple
The A/D conversion error means that measured as HART
signal which is A/D converted from the analog input signal.
The D/A conversion error of this transmitter is relatively
very small so that it does not really affect the unit’s overall
performance.
Input resistance: ≥ 1 MΩ
Burnout sensing: 130 nA ±10 %
■ RTD (2-wire, 3-wire or 4-wire)
Excitation: 0.2 mA ± 10 %
Allowable leadwire resistance: Max. 20 Ω per wire
■ Resistance (2-wire, 3-wire or 4-wire)
Excitation: 0.2 mA ±10 %
The “Accuracies” given in Table 1 therefore equals the A/D
conversion error.
The temperature drift (coefficient) or the cold junction
compensation error is not included in the “Accuracy.”
Allowable leadwire resistance: Max. 20 Ω per wire
■ Potentiometer
Excitation: 0.2 mA ±10%
■ CALCULATION EXAMPLES OF OVERALL ACCURACY IN %
• DC Voltage
Allowable leadwire resistance: Max. 20 Ω per wire

2) 0 – 4 mV
OUTPUT SPECIFICATIONS
Output range: 4 – 20 mA DC
Operational range: 3.8 – 21.6 mA
Load resistance vs. supply voltage:
Load Resistance (Ω) = (Supply Voltage (V) – 12 (V))

CJC error (0.5°C) added: 0.25 + 0.5 = 0.75°C
0.75°C ÷ (150 – 50)°C × 100 = 0.75 %

Absolute value accuracy (Table 1): 0.15°C
