2.3.1 - Milliampere Input
A standard 4 to 20mA current source can be applied between terminals 1(+) and
3(-) in case of input 1, and between terminals 4(+) and 6(-) in case of input 2; such
current can originate from an externally powered Transmitter. In the event that the
internal controller 24V voltage source is used to power a 2-wire Transmitter the current is
received only on terminal 1(+) in case of input 1 and received only on terminal 4(+) in
case of input 2. Figure 4 illustrates those two connection possibilities.
