PRODUCT OVERVIEW
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
NEMA enclosure.
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”
arrangement.
Modules are “Hot Swappable”; power does not have to be
removed when inserting or removing any module on the
backplane.

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.
Figure 1 illustrates the 3B Series backplane functional block
diagram. In addition, complete specifications are shown in the
table below.
