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 and the DI-78B expansion unit accepts DI-8B modules.
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 contaminants.
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.
The DI-8B Series has no pots to adjust. Simply choose the module, function, and measurement range, then install it in the instrument (the DI-718B). Now connect your input signals. The instrument becomes a direct sensor interface, outputting a perfectly conditioned, ±5V signal (ideal for WinDaq software).
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 position.
