mA Output loop resistance
Figure 4-5: mA Output: loop resistance
A. Loop resistor (ohms)
B. Supply voltage VDC (V)
C. Rmax = maximum value of loop resistor allowed
D. Rmin = minimum value of loop resistance required
Loop resistance equation
Rmax = (Vsupply − 10V) / 0.023
Rmin = 0 Ω, Vsupply ≤ 25V
Rmin = 200 Ω, Vsupply > 25V
4.6.2 Wire the Frequency Output or Discrete Output for
nonhazardous installations
Wire the Frequency Output or Discrete Output in explosion-proof, nonincendive, or nonhazardous
installations.
Prerequisites
WARNING
Meter installation and wiring should be performed only by suitably-trained personnel using the appropriate
government and corporate safety standards.
Procedure
