OUTPUT SPECIFICATIONS
Output range: 4 – 20 mA DC
Operational range: 3.75 – 23 mA
Load resistance vs. supply voltage:
Load Resistance (Ω) = (Supply Voltage (V) – 8 (V)*) ÷
0.023 (A) (including leadwire resistance)
*12 (V) with LED indicator option.
HOW TO CALCULATE ACCURACY AGAINST SCALE
Example: 4 – 20 mA input, Scale 0 – 100
Burnout: 3.75 – 3.8 mA or 21.5 – 23 mA
(factory set to 23 mA)
Accuracy = 0.01 mA ÷ (20 – 4)mA × 100 = 0.063 %
Display Error = (100 – 0) × 0.063 % = ±0.063 digits
Upper output limit proportional to the input:
20 – 21.5 mA (factory set to 21.5 mA)
Lower output limit proportional to the input:
3.8 – 4 mA (factory set to 3.8 mA)
