Function Range

1. INTRODUCTION

The data logger ALMEMO
product range of measuring devices that are all equipped with the ALMEMO
connector system, which has been patented by Ahlborn GmbH. The intelligent
®
ALMEMO connector provides important advantages with regard to the
connection of sensors and peripherals as all parameters are stored in an
EEPROM within the connector. As a result, the programming that usually has
to be performed for the connection is not required. All sensors and output
modules can be connected to all ALMEMO
way. The operation and programming is identical with all units. Therefore, all of
®
the ALMEMO measuring system items listed below are described, in detail, in
a separate ALMEMO
Detailed description of the ALMEMO
Overview of the device functions and measuring ranges (manual section 2)
All sensors with basic principles, operation, technical data (man. section 3)
The options for connecting existing sensors (manual section 4)
All analog and digital output modules (manual section 5.1)
The interface module RS232, fiber optics, Centronics (manual section 5.2)
The entire ALMEMO
All functions and their control via the interface (manual section 6)
A complete interface command list with all print outputs (manual section 7)
These operating instructions only cover features and controls that are specific
for a certain device. As a result, many sections will often provide a note
referring to the more detailed description within the manual (man. sect. x.x.x).
1.1 Function Range
®
The ALMEMO 2590-9 data logger has 9 electrically isolated measuring inputs
with up to 36 measuring channels for more than 65 measuring ranges, a real
time clock and a 500kB memory for approximately 100000 measured values.
External memory devices can be attached as an option. The device can be
operated by means of the LCD graphic display, a softkey keypad and an
operating dial. User menus can be configured to adapt the display for any
application. Two output sockets allow for connecting any ALMEMO
modules, for example, the analogue output, digital interface, trigger input or
alarm contacts. Several devices can be networked by simply connecting them
with network cables.
SENSOR PROGRAMMING
The measuring channels are automatically programmed by the ALMEMO
connectors. However, the user can easily complete or modify the programming via
keyboard or via interface.
