What
is Functional Safety?
|
|
|
| We
begin with a definition of safety . This is freedom
from unacceptable risk of physical injury or of
damage to the health of people, either directly
or indirectly as a result of damage to property
or to the environment. Functional
safety is part of the overall safety that
depends on a system or equipment operating correctly
in response to its inputs.
For example, an over-temperature
protection device, using a thermal sensor in
the windings of an electric motor to de-energise
the motor before they can overheat, is an instance
of functional safety. But providing specialized
insulation to withstand high temperatures is
not an instance of functional safety (although
it is still an instance of safety and could
protect against exactly the same hazard). Neither
safety nor functional safety can be determined
without considering the systems as a whole and
the environment with which they interact.

At
Prodigy, we understand the obvious risks associated
with failure, safety requirements of each application
are unique. Prodigy's domain expertise in Functional
Safety ensures thorough analysis of the given requirement
and identifying the cases of vulnerability, suggesting
required level of redundancy in hardware and processing
capacity needed for fault tolerance techniques. We
provide the best solution to meet or exceed the mandatory
set by the relevant standards yet at low cost.
Prodigy's modular
safety controller products for safety solutions are
high reliable and tightly controlled. The modules
are tested for reliability to withstand harsh environment
as per the European Functional Safety Standards. With
the tested and trusted rich set of software modules,
the safety controller modules are software configurable,
expandable, easy-to-commission that can be efficiently
adapted to a variety of safety applications for small-
to large-sized applications. |
