Description
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 DI720 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. 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 DI-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 DI-78B is powered by the host DI-720 or DI-730 unit using a supplied jumper cable.
