Product Highlights
Model DI-78B is a backpack expander for DI-720 and DI-730
products. The DI-78B is a sleek unit that has exactly
the same footprint and height as DI-720 and DI-730 products,
yielding an extremely capable yet compact solution for
industrial measurements. The unit measures 9L ×
7.29W × 1.52H inches (22.9L × 18.5W ×
3.86H cm). It accepts up to sixteen 8B style modules and
therefore brings the universe of isolated industrial measurements
to DI-720 and DI-730 products. These include thermocouple,
voltage, strain, frequency, process current, RTD, and
potentiometric. Soon to be released is a line of RMS measurement
modules. These measurement modules may be mixed and matched
within the DI-78B backpack in any combination suitable
for the application. Signal connection is via four removable
screw terminal blocks.
A maximum of one 78B may be used with either the DI-720
or DI-730 to yield as many as sixteen 8B-conditioned inputs
in addition to any remaining channels provided by the
host data acquisition product. The 78B is powered by the
host DI-720 or DI-730 unit using a supplied jumper cable.
Make Industrial Measurements Through DI-8B Plug-in
Signal Conditioning Modules
The DI-78B brings isolated, industrial-type measurement
capability to DI-720 and DI-730 instruments. Add the DI-78B
for a complete, easy, and convenient signal conditioning
solution. Each channel consumes one channel from its host
instrument in return for the isolated, signal-conditioned
input it provides. One DI-78B may be connected to any
DI-720 or DI-730 instrument to add 16 signal-conditioned
input channels in addition to any remaining channels on
the host instrument.
Each channel on the DI-78B accommodates one DI-8B module,
which provides a single channel of isolated input protection,
amplification, and filtering. Measuring only 1.105? ×
1.65? × 0.40? DI-8B modules are the smallest signal
conditioning modules available. DI-8B modules are plugged
into a socketed backplane and are secured with a mounting
screw. Each channel has four corresponding screw terminals
for your signal connections: channel +, channel -, excitation
+, and excitation -. These terminals satisfy all transducer
inputs and provide sensor excitation when necessary. Access
to the DI-8B modules is through a removable top panel.
Flexible Power Requirements
When used with either a DI-720 or DI-730, the DI-78B can
be powered by these instruments through a supplied, dual-ended
power cable.
Similar Footprint
The DI-78B has the same dimensions as our DI-720 and DI-730
instruments (9?L × 7.29?W × 1.52?H). This
allows the DI-78B to be easily stacked and mounted to
the host instrument with an optional hardware mounting
kit.
Easy to Connect
The DI-78B connects to the host instrument in seconds
with the supplied interconnecting cable. Simply connect
one end of this cable to the EXPANSION port on the host
DI-720 or DI-730 instrument and connect the other end
to EXPANSION IN on the DI-78B's rear panel.
Convenient Signal Connection
Four removable screw terminal blocks allows signal connections
to be made to the DI-78B quickly and easily. A convenient
pinout sticker on the top of the instrument clearly shows
where signal connections should be made.
Stackable with Included Hardware
The included stacking brackets allow the DI-78B to be
stacked and mounted to the host instrument. The stacking
brackets come complete with mounting hardware to make
installation a snap. An optional stainless steel carrying
handle is also available for convenient system handling.
