Universal transmitter 8390-1

1. INTRODUCTION

The universal transmitter ALMEMO

®

8390-1 is a new member in our family of

unique measuring devices
- all equipped with Ahlborn GmbH’s patented ALMEMO

®

connector system.

The intelligent ALMEMO

®

connector offers decisive advantages when con-

necting sensors and peripherals because all parameters are stored in an EE-
PROM on the connector itself; repeat programming is thus no longer necessa-
ry.
All sensors and output modules can be connected to all ALMEMO

®

measuring

instruments - all in the same way. Programming and functioning are largely
identical for all units. The following points apply to all devices in the ALME-
MO

®

measuring system and are described in detail in the ALMEMO

®

Manual

supplied with each device.

•

Detailed description of the ALMEMO

®

system (Manual, Chapter 1)

•

Overview of the device functions and measuring ranges
(Manual, Chapter 2)

•

Basic principles, operating instructions, and technical data for all sensors
(Manual, Chapter 3)

•

Options for connecting your own existing sensors (Manual, Chapter 4)

•

All analog and digital output modules (Manual, Section 5.1)

•

Interface modules RS-232, optic fiber, Centronics (Manual, Section 5.2)

•

The entire ALMEMO

®

networking system (Manual, Section 5.3)

•

All functions and their operation via the interface (Manual, Chapter 6)

•

Complete list of interface commands with all the printouts
(Manual, Chapter 7)

The operating instructions you are now reading cover only those features and
controls that are specific to this device. They often refer to a more detailed
explanation in the Manual (Manual, Section x.x.x).

1.1 Functions

Universal transmitter ALMEMO

®

8390-1 has one measurement input for all

ALMEMO

®

sensors. The measuring possibilities are virtually unlimited; there

are 4 channels in the sensor connectors - with over 70 measuring ranges.
ALMEMO

®

output modules, analog output, or a digital interface can be con-

nected to the output socket. Several devices can be networked via ALMEMO

®

network distributors. Sensors can be programmed and measuring instruments
can be configured for data output as and when necessary via the interface and
this is best performed using the accompanying AMR-Control software packa-
ge. A wall mounting is included in delivery. Available options include one or
two integrated analog outputs, an RS-485 interface, or even an Ethernet con-
nector.
