motor management and control devices
Expansion with additional inputs/outputs by means of an
analog module
Basic unit 2 can be optionally expanded with analog inputs and
outputs (0/4 ... 20 mA) by means of the analog module. It is then
possible to measure and monitor any process variable that can
be mapped on a 0/4 ... 20 mA signal. Typical applications are,
for example, level monitoring for the implementation of dry run-
ning protection for pumps or monitoring the degree of pollution
of a filter using a differential pressure transducer. In this case the
automation system has free access to the measured process
variables. The analog output can be used, for example, to visu-
alize process variables on a pointer instrument. The automation
system also has free access to the output.
Maximum one analog module can be connected to one basic
unit 2. Both inputs are set to a measuring range of either
0 ... 20 mA or 4 ... 20 mA.
Safe isolation
All circuits in SIMOCODE pro are safely isolated from each other
in according to IEC 60947-1. That is, they are designed with
double creepage and air distances. In the event of a fault,
therefore, no parasitic voltages can be formed in neighboring
circuits. The instructions of test report No. 2668 must be
complied with.
EEx e and EEx d types of protection
The overload protection and the thermistor motor protection of
the SIMOCODE pro system comply with the requirements for
overload protection of explosion-protected motors to the degree
of protection:
• EEx d "flameproof enclosure" e.g. according to EN 50018 or
EN 60079-1
• EEx e "increased safety" e.g. according to EN 50019 or
EN 60079-7
When using SIMOCODE pro devices with a 24 V DC control
voltage, electrical isolation must be ensured using a battery or a
safety transformer according to EN 61558-2-6.
