choosing a ABB safety system
for a smal ESD system(100 I/O) which ABB safety system is suitable? safegaurd,plantgaurd or high integrity independent system or there is other solution? which one is cheaper?
if safegaurd and plantgaurd are available for next years?
Hopefully ABB will support Safegaurd and Plant gaurd for further 10 to 15 years.
Now preset market product is Hi intigrity (AC 800M -PM865).
Technically Both are good.
As per my Knowlodege AC800M will cheaper comparetively but you have to confirm with bids team of ABB.
AC 800M is based on New tecnology , So I prefer Hi intigrity system.
Its my opinion.
Is it possible to share industry and application area?
Industry - process automation, power generation (and additional info - i.e. OG, Chemical and so on)
Application - FF, BMS, Boiler etc.
Customers expect solution based on their standards and local requests (given by agencies, goverment regulations and so on). After that you can choose suitable ESDS based on teh request, not price.
AC800m HI system is a scalable solution as compared to Safeguard or plant guard system and hence will be price optimial.
Also, HI system will be relased with a version, certified for latest IEC 61508 edition2 standards
Taking latest technology and certification in to account, you shall choose HI sytem only.
For applications in the process industries from 50 I/O channels up, the best solution today is Independent High Integrity, it's not only better from the price/value point of view but also provides a better lifecycle support for the user considering it's a more modern architecture. High Integrity is in the Active phase of its lifecycle, both Safeguard and Plantguard are in Classic
Safeguard and Plantguard were designed to satisfy Safety Integrity Level using the redundancy of the architecture, Indpendent High Integrity offers flexibility to adapt the redundancy to the actual requirements of the application
There are additional advantages in the ease of programming and integration capabilities that also impact cost
In summary Independent High Integrity is your most cost competitive choice to meet safety needs in the process industries
