Channel power requirements
The supply voltage required by the 4200 transmitter depends on the total resistance in the
mA loop. This includes all sense resistance and wire resistance.
Channel A mA HART terminal requirements
Use the chart below to determine the required supply voltage for Channel A based on loop
resistance.
Figure 3-1: Channel A output supply voltage and loop resistance
A. Loop resistance (Ohms)
B. Supply voltage (Vs)
C. Maximum Loop Resistance (Ohms)
Table 3-2: For maximum loop resistance for Channel A
Condition
Equation
17.75V < Vs <19.6V
(Vs-17.75)/3.6mA
19.6V < Vs < 21.5V
(Vs-8.32V)/22mA
21.5V <Vs <30V
600 ohms
Note
If display backlighting is enabled (refer to
Configure the display backlight
input voltage required is 1V higher than the chart indicates.
