Wiring
Your 870IT is a 2-wire transmitter. As such, it transmits output over the same two wires through
which it receives power. If your transmitter was specified with analog communications
(870ITPH-A), you must supply its power source. If it was specified with digital communications
(870ITPH-F), power can be provided via the I/A Series Fieldbus Module. Connect this
power/output signal and the signal from your measurement sensor as follows:
1. Open the hinged case door.
2. Remove the plastic shipping caps from the openings on the bottom of the case and
replace with proper fittings. You will be running wires through the left and right
openings and capping the middle opening.
