To address diverse applications, the 3B Subsystem Series
includes a family of backplanes which provide a complete signal
conditioning solution. The 3B01backplane is designed for 16
channels, to offer users the flexibility to match the size of a
system to specific applications. All backplanes are provided with
#6-32 x 1-inch screws and standoffs for mounting. Several
mounting options are available, including rack, surface and
All 3B Series modules feature a universal pin out and can be
easily tailored to fit the user's application. Each backplane can
accommodate any 3B Series module in a "Mix and Match"
Modules are "Hot Swappable"; power does not have to be
removed when inserting or removing any module on the
All backplanes provide a four screw terminal for each individual
channel's input field connections. These connections satisfy all
transducer inputs and provide transducer excitation when

A cold junction temperature sensor is also supplied on each
channel to accommodate thermocouple input modules.
Each channel has two screw terminals for the output
connections for the 4-20 mA output signals. Two 26-pin system
connectors provide high level voltage I/O for all channels.

The 3B01 Series backplane provides the user with sixteen
Channels, any of which may be used with any of the 3B series of
modules offered by ADI.
This backplane have been designed to operate in a wide
temperature range, from -25
C up to +85
The 3B01 Series backplane has been evaluated by both Factory
Mutual and also by CSA. The 3B01 has passed all agency testing
and is listed by both organizations. In addition the 3B01 series
back plane is also CE certified.
The 3B01 backplane has several mounting options:
o Surface Mount stand alone or using Surface Mount
Kit, model AC1331
o 19-inch Rack Mount Kit model AC1330
