System description

Analog module (AM)

By means of the analog module, basic unit 2 can be optionally expanded by

analog inputs and outputs (0/4 mA - 20 mA). As a result, it is possible to

measure and monitor any process variable that can be mapped on to a 0/4

mA - 20-mA signal.

Typical applications would be, for example, fill-level monitoring for

protecting pumps from dry operation, or the monitoring of pollution in a

filter using a differential pressure transducer. The automation system has

free access to the measured process variables. The analog output can, for

example, be used for the visualization of any process variables on a pointer

instrument. The automation system can also freely access the output via

• 1 analog module can be connected to BU2

• 2 analog inputs (passive) for measuring 0/4mA - 20 mA signals.

Both inputs are either set to 0 - 20 mA or 4 mA - 20 mA

• 1 output for outputting a 0/4 mA - 20 mA signal.

The inputs of the analog module are passive inputs that have to be supplied

by an external, isolated current source (e.g. isolating transducer). If the

output of the analog module is not being utilized, it can be used as current

source for an input.

The use of an analog module requires basic unit 2, version *E02*

(from 04/2005).
