Note

This manual contains information and warnings that must be followed to ensure safe operation and retain the instrument in safe condition.

The Hydra Series II Data Acquisition Unit

The Hydra Series II Data Acquisition Unit (Model 2620A) is a multi-channel data acquisition unit able to measure ac and dc voltages, temperature via thermocouples and RTDs, resistance, and frequency. It features 21 measurement channels, 8 digital input/output lines, a Totalizer input, and 4 alarm output lines. The Data Acquisition Unit is easily carried by hand and can be ac or dc powered. The user can choose communications with a host computer over an RS-232 (standard) or IEEE-488 (2620A/05) computer interface. Refer to Table 1-1 for a list of operating features.

The Hydra Series II Data Logger

The Hydra Series II Data Logger (Model 2625A) combines data logging memory with the features of the Data Acquisition Unit. The RS-232 computer interface is standard (IEEE-488 capability is not available.)

Options and Accessories

Applications Software

The following software packages are available for the instrument:

∙Hydra Starter (included with instrument)

Allows for communication from an IBM-compatible personal computer through the RS-232 interface, emphasizing transfer of measurement and configuration settings to and from the instrument.

∙Hydra Logger Package (order separately)

Hydra Logger (model 2635A-901) is a Windows-based package that allows complete set up and data collection and data conversion from up to 2 Hydra units. Logger communicates over the RS-232 port on a personal computer and may be used with telephone modems. Hydra Logger with Trending (model 2635A-902) includes a comprehensive trending package that simulates a chart recorder. A brochure with complete details is available.

IEEE-488 Interface Assembly

Model 2620A/05 includes an IEEE-488 Interface. Commands for the IEEE-488 interface are virtually identical to those used with the RS-232 Interface

If your Hydra Series II Data Acquisition Unit does not have an IEEE-488 Interface, a field-installable kit (2620A-05K) is available. The Hydra Series II Data Logger cannot be equipped with an IEEE-488 Interface.

Connector Set (2620A-100)

The 2620A-100 is a complete set of input connectors (one Input Module and two Digital I/O Connectors). These connectors allow for additional wiring setups so that a single Hydra Series II Data Acquisition Unit or Data Logger can then be moved among multiple installations.
