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.
