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.

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

necessary.

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.
