Data Acquisition System SA 32 - AOIP - #1

The SA32 is intended to measure, hande, monitor and log record analogue signals Desgned with both flexibility and precson in mind, this system can be used in numerous applications such as

- data coiection in the field

- research or quality laboratories

- acquistion interface for calculator or computer

- process monitoring.

Different veraons of the SA32 are availabe:

• With keypad and dspay

• With keypad, dspay and FtMQAinterface,

• Without keypad, dspay neither FCMOA interface.

SA32 allows programming of 100 ad­dresses, which can be defined to measure real channels (up to the system limit of 32 channels max) or virtual channels used to perform calculations/ maths functions.

Each channel can be assigned a 4 char­acter engineering units label, an 8 char­acter mnemonic and the following func­tions:

• Monitoring

4 alarm limits per channel, different for each channel SA 32 is equipped with 2 output relays addressable to any limit

• Maths functions

Available as standard are the operators +, -,/ ,x, elevation to multiple powers, timer function(s), logic operators, square root, log decimal, absolute value and sta­tistical functions min, max, average, stan­dard deviation.

• Conditional functions

Such as IF, THEN, DO allowing condition­al modification of parameters and change

of scanning speed or of criteria for stor­age in memory.

Input channels are scanned by a CMOS logic circuit

Scanning is organised in «tasks» or scan­ning procedures, defining what to scan (channels), how to scan (scanning start and stop, scanning rate), and how to process the results (mass storage, RS232 output). The user has access to 16 tasks, therefore 16 different scanning sub­groups.

or via RS232 interface with the assistance of IS32 DOS software supplied with the unit

Backlit LCD give simultaneous display of 2 channels in either digital or graphical for­mat (150 points definition) on a time base adjustable between 1 sec. to 1 min. It also permits recall of the storage memory in order to display recorded data in digi­tal or graphic form.

The logger is programmable entirely via the keyboard and help menu on screen,
