INTRODUCTION

The data acquisition module ALMEMO ® 5690-1M is a new member in our
family of unique measuring devices - all equipped with Ahlborn's patented AL-
MEMO ® connector system. The intelligent ALMEMO ® connector offers deci-
sive advantages when connecting sensors and peripherals because all pa-
rameters are stored in an EEPROM located on the connector itself; repeat
programming is thus no longer necessary.
All sensors and output modules can be connected to all ALMEMO ® measuring
instruments in the same way. Programming and functioning are identical for all
units. The following points apply to all devices in the ALMEMO ® measuring
system; these are described in detail in the ALMEMO ® Manual which is in-
cluded in delivery with each device:
Detailed explanation of the ALMEMO ® system (Manual Ch 1)
Overview of the device functions and measuring ranges (Manual Ch 2)
Basic principles, operation, and technical data for all sensors (Manual Ch
3)
Options for connecting your own existing sensors (Manual Ch 4)
All analog and digital output modules (Manual 5.1)
Interface modules RS-232, optic fiber, USB, Ethernet (Manual 5.2)
The whole ALMEMO ® networking system (Manual 5.3)
All functions and their operation via the interface (Manual Ch 6)
Complete list of interface commands with all the printouts (Manual Ch 7)
The operating instructions you are now reading cover only those features and
controls that are specific to this device. Many sections therefore also refer to
the more detailed description in the Manual; (see Manual, Section xxx).
4.1 Functions of the ALMEMO
The data acquisition system ALMEMO ® 5690-1M has basically 9 electrically
isolated measuring inputs with over 70 measuring ranges - suitable for all AL-
MEMO ® 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 12-DU / 32-DU / 84-DU sizes and a 19-inch
rack is available. Thanks to the real-time clock incorporated as standard and
the external memory connector with multimedia card the amount of data you
can record is virtually endless. A variant is available with an integrated 512-KB
EEPROM memory sufficient for approx. 100,000 measured values. There are
two output sockets which can be used to connect any ALMEMO ® output mod-
ules, e.g. analog output, digital interface, memory connector, trigger input, or
alarm contacts. Several devices can be networked by simply connecting them
with network cables.
The system is fed by default via a 12-V mains adapter. There is also the option
