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
PROFIBUS.
• 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.
Notice
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.
Note
The use of an analog module requires basic unit 2, version *E02*
(from 04/2005).
