Model DI-788 is a 32-channel data acquisition system based on our 8B-style modular signal conditioners (view the DI-8B module selection guide) and Third Generation Ethernet (3GE) communications. The DI-788 is packaged in an enclosure that measures 16.5W × 18.5D × 3.5H inches (41.9W × 47D × 8.9H centimeters) that is suitable for placement on a desktop, or can be mounted in a standard 19-inch rack using optional brackets. It’s also the first product from DATAQ Instruments to feature a built-in switching AC power supply, allowing it to be powered directly from AC line voltage.
The DI-788 features similar data acquisition performance as our model DI-720-EN, but is supplied with two built-in 16- channel 5B module backplanes allowing up to 32 DI-8B modules to be installed bringing the universe of isolated industrial measurements to the DI-788. DI-8B modules can measure thermocouple, voltage, strain, frequency, process current, RTD, potentiometric, and RMS. Modules may be mixed and matched in any combination suitable for your application. Signal connection is via eight removable screw terminal blocks.
The DI-788 can connect to any local area network (LAN), and direct Internet access is also possible when allowed by the network. The interface uses CAT-5 cable to yield continuous data acquisition rates up to 180,000 samples per second throughput for a single DI-788. Multiple DI-788s connected to the same network can achieve throughput rates as high as 2,500,000 samples per second or more. Adding more flexibility, multiple DI-788s, as well as DI-720/-730 products, each equipped with an Ethernet interface, may be daisy-chained together with CAT-5 cable to form an ad-hoc extended network of autonomous, yet fully synchronous data acquisition stations. Each station can sample at the same or different rate as other stations and still maintain full synchronization. The maximum distance between stations is 100 meters. This daisy-chained, synchronous aspect of the product is patented (US 7,792,139 B2).
