PRODUCT OVERVIEW
To address diverse applications, the 3B Subsystem Series
includes a family of backplanes which provide a complete signal
conditioning solution. The 3B03 is designed for 4 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.
