Introduction; Functions Of The Almemo 5690-2M - Ahlborn ALMEMO 5690-2M Operating Instructions Manual

5. Introduction

5. INTRODUCTION
The data acquisition system ALMEMO
ily of unique measuring devices - all equipped with Ahlborn's patented
®
ALMEMO connector system. The intelligent ALMEMO
sive advantages when connecting sensors and peripherals because all parame-
ters are stored in an EEPROM located on the connector itself; repeat program-
ming is thus no longer necessary.
All sensors and output modules can be connected to all ALMEMO
instruments in the same way. Programming and functioning are identical for all
units. The following points apply to all devices in the ALMEMO
system; these are described in detail in the ALMEMO
cluded in delivery with each device.

controls that are specific to this device. Many sections therefore also refer to
the more detailed description in the Manual; (see Manual, Section xxx).

5.1 Functions of the ALMEMO 5690-2M

The data acquisition system ALMEMO
isolated measuring inputs with over 70 measuring ranges - suitable for all
®
ALMEMO sensors. This number can, using various selector switch boards,
be extended to 99 inputs. To accommodate these various expansion stages
the desktop housing is available in 32-DU / 84-DU sizes and a 19-inch rack is
available. For operation purposes the device incorporates an LCD graphics
display and a soft-key keypad with cursor block. The display can be adapted
by means of configurable user menus to suit any application. Thanks to the
real-time clock incorporated as standard and with a SD card the amount of
data you can record is virtually endless. A variant is available with an inte-
grated 512-KB EEPROM memory sufficient for approx. 100,000 measured val-
ues. With optionally Module RTA5 available to 10 internal connections any
®
ALMEMO output modules, e.g. analog output, digital interface, trigger input,
or alarm contacts. Several devices can be networked by simply linking them
together via cable.
The system is fed by default via a 12-V mains adapter. There is also the option
of using a rechargeable battery module.
