Section 2 SAM600 Process Bus I/O System
2.1 System overview
GUID-300360E0-8897-4ACA-A73C-3BF75903163E v1
SAM600 process bus I/O system is a modular, extensible, and customizable product solution
that converts signals from the primary analog process to its digital counterpart according to
the IEC 61850 standard.
The product is designed for both AIS and GIS applications. It can be beneficially applied to
secondary system upgrades as well as new substation installations, thus integrating
seamlessly with modern sensor technology.
SAM600 optimally tailors to different applications, is prepared for placement in harsh outdoor
setups and can be deployed in a stepwise manner in marshalling kiosks close to primary
apparatus, or in existing secondary system protection and control panels.

SAM600 process bus I/O system provides unique features with focus on adaptability to
different application types, easy installation and maintenance for integration into existing
secondary systems or for new installations.
• A SAM600 module per primary apparatus interfaces conventional current or voltage
transformers and provides standalone merging unit (SAMU) functionality according to the
IEC 61850-9-2 standard.
• DIN-rail mountable SAM600 modules with a compact form factor can be placed close to
the primary apparatus. SAM600 modules support operating temperature ranges between
-40°C to +70°C.
• Each SAM600 module terminates main signals from the process (for example, voltages
and currents), as well as auxiliary signals (fuse failure and test switch indication), thus
avoiding cross-wiring and simplifying replacement and maintenance activities.
