8.10 Analog module (AM)
By means of the analog module, the SIMOCODE pro V High Performance basic units can be
optionally expanded by analog inputs and outputs (0/4 mA to 20 mA). This makes it possible
to detect and monitor any process variables that can be mapped onto a 0/4 to 20 mA signal.
Typical applications are, 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 the communication
bus.
● 1 analog module can be connected to the SIMOCODE pro V PB and
pro V MR basic units
● 2 analog modules can be connected to the SIMOCODE pro V PN and
pro V EIP basic units
● For each analog module, 2 analog inputs (passive) for detecting 0/4 mA to 20 mA signals.
Both inputs are set either to 0 mA to 20 mA or to 4 mA to 20 mA.
● For each analog module, 1 output for issuing a 0/4 mA to 20 mA signal.
Note
The inputs of the analog module are passive inputs that have to be supplied in each case by
an external, isolated current source (e.g. isolating transformer). If the output of the analog
module is not being utilized, it can be used as current source for an input.
Note
Requirements for using an analog module with SIMOCODE pro V PB
Use of an analog module requires a SIMOCODE pro V PB basic unit, at least version *E02*
or later (from 04/2005).
