Insulation resistance
: ≥ 100 MΩ with 500 V DC
Dielectric strength
: 2000 V AC @1 minute (input to output to power to ground)
CALCULATION EXAMPLES OF OVERALL ACCURACY
[Example] Input Span 60°, Output Range 0 – 20 mA, Output Setting 4 – 20 mA
■
Overall accuracy
• Input Accuracy = Input (60°) × Input Accuracy (0.2 %) = 0.12°
0.12°< 0.5° thus
Input Accuracy = (0.5°) ÷ 60° × 100 = 0.83 %
• Output Accuracy = Output Range Span (20 mA) ÷ Output Span Setting (16 mA) × 0.04 % = 0.05 %
Overall Accuracy = 0.83 + 0.05 = ±0.88 %
