Alternatively, Profibus-configured Model 1056 can be wired to a Profibus network using an M12 adaptor cable
assembly. The adaptor assembly kit accessory offered by Rosemount Analytical is designed to connect to a stan-
dard Profibus network T-cable which is directly connected to the Profibus network.
The M12 cable adaptor assembly is an ordering option. The kit is not provided with the Profibus-configured Model
1056. See Sec. 6.0 Profibus Accessories for ordering information.
The M12 cable adaptor is an interconnect cable
between the communications board and the Profibus
network. The 5-pin female connector on the fitting end
of the M12 cable adaptor allows direct interface to a
Profibus network. The M12 cable adaptor kit includes:
a. threaded metal adaptor fitting with soldered
4-lead cable and ground wire
b. threaded metal nut and o-ring to secure metal
fitting and cable to enclosure through an opening
