DB78HD Breakout Board with Spring Terminals
- DB78HD connector
- Perfect for prototyping DAQ and I/O board connections
- Spring terminal for each of the 78 lines, plus shield
- Rubber feet or DIN rail mount
General Description
Make connections quickly and reliably with this breakout board, which brings every pin of its DB78HD connector out to spring terminals. This product is available with both male and female connectors.
This breakout board features push-in spring connection terminal blocks. These screwless spring clamp terminal blocks allow connections to be made very quickly and efficiently. The spring terminal connections are reliable and secure, but wires can be connected and disconnected in a fraction of the time required with standard screw terminal blocks. Simply depress the actuator button on top of the terminal block, insert or remove the wire, and release the button. Done! In addition, screwless spring connections can offer better results in environments where vibration could potentially loosen standard screw terminal block connections. If your application requires screw terminals rather than spring terminals, please consider the BRK78HD design or the other DB78HD options listed here.
This breakout board is perfect for production applications as well as experimentation and prototype work. It is helpful for working with I/O cards, Data Aquisition (DAQ) devices, and other devices that use a DB-78HD connector.
Technically, the correct term for a DB78HD connector is DD78, but that term is not commonly used.
Need something different? We stock a variety of DB78HD breakout board styles and form factors. Please have a look!
A breakout board is sometimes referred to as a "transition module", "terminal board", "terminal block", "breakout box", "breakout adapter", "terminator", or "interface module".

Connector Style
These breakout boards are available with either a Right Angle connector or a Straight ("Vertical") connector. The terms Right Angle and Straight refer to the connector itself, NOT the relationship of the mating cable to the plane of the PCB. In fact, the cable mating to a Right Angle connector is parallel to the PCB, while the cable mating to a Straight connector is perpendicular to the PCB. These are pictured below:

These products are available in two different mounting variants. Product numbers ending with -DIN come with DIN clips already installed and ready to snap onto 35mm or 32mm DIN rail. Product numbers ending with -FT have stick-on rubber feet installed on the bottom side, allowing for benchtop use or panel mounting. For panel mounting, we suggest 1/4" nylon standoffs under the mounting holes, and #6 screws.BRKG78HDF-S-DIN
