Gas Control Panel Now SIL 3 Approved

Galileo SMS gas control panel from Sensitron (Italy) has been designed and approved to comply with the SIL (Safety Integrity Level) requirements according to the European Standard EN50402 on Functional Safety and has reached the SIL 3-C Level. Extremely flexible and highly reliable, it allows monitoring gas detectors connected with both 4-20

mA transmission and on addressable loops.

The functional safety is aimed to supervise and manage the behaviour of a system in case of failures. When defining the system structure all possible different types of failures that may occur in any part of the system are to be considered and evaluated.

The control unit`s main board is designed around 2 powerful microprocessors, that communicate one to each other the monitored data ensuring the complete availability of all main board functions even in the case of a failure in one microprocessor.

A broad range of self-testing facilities are implemented to detect and localize possible faults. The redundancy offered by every module being part of the system, added the possibility to communicate with remote input/output modules via a redundant BUS and with each detector via

double connection (analogue and addressable), makes this system comply with the Functional Safety requirements of EN 50402 up to SIL3. The range is also completed by the GALILEO S 8 that has been designed for small systems up to 8 analog detectors and the GALILEO S 32 where up to 32 detectors are connected on a addressable closed loop.
