Measurement of sinusoidal alternating signals (voltage or current)
Direct input up to 250A and 1000V
Galvanic isolation (up to 5000V)
Accuracy: +/- 0.5%
CAL45CA: measures 5A AC/DC; 500V AC/DC
CAL45CAD: measures up to 50A AC; 1000Vac
The CAL45CA family of measurement converters converts AC voltages or currents (
) into a 4–20 mA current proportional to the input value. The use of 2-wire technology (
, where the converter is powered by the 4–20 mA loop) simplifies wiring.
