Safety platform is certified for SIL 2
The SafetyNet functional safety platform has been certified by TUV Rheinland for use in SIL 2 safety functions.
MTL Open System Technologies (MOST), a member of the MTL Instruments Group, has announced that its SafetyNet functional safety platform has been certified by TUV Rheinland for use in SIL 2 safety functions Solution providers using MOST's products can now meet the safety needs of emergency shutdown (ESD), fire and gas (F and G), burner management (BMS) applications and - together with MOST's process control platform - they can also meet the needs for integrated control and safety systems (ICSS)

Redundancy boosts Fieldbus reliability
Redundancy of the Fieldbus power supplies will eliminate the risk of network failure in the event of loss of a single supply unit.
Safety isolators cut power consumption
The reduced power consumption and high efficiency of the isolators enables high signal densities to be achieved, together with improved freedom in cabinet layout and design.
"SafetyNet hits a sweet spot in today's market", says Dil Wetherill, Business Development Manager for MOST.
"As safety system companies and end users apply IEC61508, they find that they have many SIL 2 safety functions which do not require the initial expense, cabinet space and on-going life costs of more sophisticated SIL 3 solutions".
"MOST's SafetyNet product offers them a real process control solution to these lower level safety functions with recognisable process control features such as Hart, hazardous area capability and high levels of availability, rather than resorting to the use of PLCs".

MTL's 9331-TI fieldbus multiplexer can reduce installed costs by as much as 70% per point when compared to traditional single-temperature inputs.
Barrier provides intrinsically safe connections
Wiring hub provides intrinsically safe spur connections from a nonintrinsically safe trunk, for connection to Foundation fieldbus H1 or Profibus-PA field devices.
SafetyNet meets the requirements for SIL 2 safety functions with simplex controllers and simplex I/O modules, although redundant controllers can be added for improved availability.
SIL 2 is achieved by designing-in a high level of diagnostic coverage - the basis of the TUV certification.
The result is a product that has a very small package size and is extremely cost effective.
SafetyNet is built on the same platform as the MOST process automation system, enabling those applying it to address their process control and functional safety needs with the same basic platform.
"The components may be applied in many different ways - regulatory and discrete control, emergency shutdown, fire and gas detection, burner management and combustion control - but we believe that there are many advantages when the engineering environment, the operator interface, the look and feel of the hardware are all be common".
"In particular, the cost of training and the risk of mistakes are reduced", says Wetherill.
As with the other MOST control components, SafetyNet is equipped to deal with harsh process environments.
With a temperature rating from -40 to +70C, G3 corrosion resistance and impressive shock and vibration operating performance, there should be no reason why you can't field mount your safety system and take advantage of cabling and installation savings - no matter how tough the operating conditions.
