The DI-8B Series is
a family of low-cost, high performance plug-in signal
conditioners. With over 90 modules to choose from that interface
to a wide variety of voltage, current, temperature, position,
frequency, and strain measuring devices, it is easy to find a
module to fit your signal conditioning data acquisition needs.
One-fifth the size of competing products, DI-8B modules offer
fully functional performance with superior specifications such as
±0.05% accuracy, ±0.02% linearity, three poles of filtering,
1000V Input-to-Output Isolation (when used with the DI-718B), 500V
Channel-to-Channel Isolation (when used with the DI-718B), low
output noise, and much more (see each module’s datasheet for a
complete list of specifications).

The DI-8B Series is a family of
low cost, high performance, plug-in signal conditioning modules.
Designed for industrial applications, these modules incorporate an
innovative circuit design using transformer-based isolation.
Combining 1500V rms continuous common mode voltage isolation, ±0.05%
accuracy, small size and low cost, the DI-8B Series is an
attractive alternative to expensive signal conditioners and
in-house designs. Our DI-718B
Series, the DI-788,
and the DI-78B
expansion unit accepts DI-8B modules.
Rugged, Uniform Package
All modules are identical in
pinout and size (1.11 × 1.65 × 0.40 inches), and are hard-potted
to protect the internal circuitry from moisture and other
All modules feature ±0.05%
calibrated accuracy and ±0.02% non-linearity. Chopper-based
amplification assures a low drift of ±1µV/°C and excellent long
term stability (see the each DI-8B module's data sheet for a
complete and accurate list of specifications).
The DI-8B Series can be easily
tailored to the needs of many applications. These plug-in signal
conditioners can be mixed and matched in any combination to adapt
to even the most demanding applications. Each module features a
simple pin-out, plugs easily into instrument-mounted sockets, and
is secured with a self-contained mounting screw.
Easy To Use
The DI-8B Series has no pots to
adjust. Simply choose the module, function, and measurement range,
then install it in the instrument. Now connect your input signals.
The instrument becomes a direct sensor interface, outputting a
perfectly conditioned, ±5V signal (ideal for WinDaq
On-Board CJ Compensation
Each input connector of the DI-8B
Series backplane is complemented by a cold junction compensation
circuit, allowing the thermocouple modules to be located in any
