the fuse only with 
one of the same 
type and rating.
Power The Interface Power Supply. Supplies power to external 
sensors as required.
Note • If operating with 28V signals only, pin 7 
may be used to supply power to pin 2, which 
creates a non-isolated mode of operation.
8 POWER GROUND
(+28 V DC Return)
Ground The Interface Power Ground.
Note • If pin 7 is used to supply power to pin 2, 
use this pin to ground pin 1. 
9 RIBBON LOW Output Asserted if the Ribbon Low feature is enabled and the
