Power Supply Requirements:
Output Signal
Ratiometric*
(0.5V to 4.5V)
0-10V
0-5V, 1-5V, 1-6V
4-20mA**
* 0.5Vdc-4.5Vdc output is ratiometric to the
nominal 5Vdc supply
** For transmitters with 4-20mA output signal,
the minimum voltage at the terminals is
12Vdc. However, the minimum supply volt-
age should be calculated using the adjacent
graph and formula.

Loop Supply Voltage (Vdc) [LSV]
LSV(min)=9(V)+[.022(A)*R L ]
Where:
LSV= Loop Supply Voltage (Vdc)
R L = R S + R W (ohms)
R L = Loop Resistance (ohms)
R S = Sense Resistance (ohms) [Measuring Instrument]
R W = Wiring Resistance (ohms)
