Self-powered 3-wire transmitter with system ground

This can be applied to any channels from 1 through 16.
The simplest wiring is to have the 'common' wire and the 'current
source' wire under the same terminal blocks screw. If the site wiring
does not permit this method, then a separate external terminal block
must be used. The device must reference its 'DCS-side' common to
ControlEdge 900 common.
