What is the advantage of using a 4 to 20 mA loop over a 0 to 10 VDC signal?
A. Higher resolution B. Longer cable runs C. Lower cost D. More accurate
Explanation: One advantage of using a 4 to 20 mA loop over a 0 to 10 VDC signal is the ability to transmit the signal over longer cable runs. This is because the current signal is less susceptible to noise and interference than a voltage signal.
