(4) 4-20 Milliamp Sensor, Analog Input 3 or Analog Input 4
The same accuracy and signal level reduction considerations stated under section
(3) 1-5 Volt
Sensor, Analog Input 3 or Analog Input 4,
apply when using a 4-20 milliamp sensor. The
switched voltage source at screw terminal #7 is designed to drive only two 4-20mA transmitters
to full scale. If a system will use more than two, the additional transmitters must be powered
from a separate supply, such as directly from the battery or another DC supply.
On the next page are two diagrams showing the connection of a 4-20 milliamp sensor to Analog
Input 3 (Figures 25 and 26):
