Controllers connect to both DIN style and traditional Rack I/O modules.

Intelligent I/O devices are seamlessly integrated through industry

standard fieldbuses and networks with resident information used in control and higher level

applications for tighter and more reliable process solutions. Inclusion of native turbine specific

modules deliver a fully integrated single-vendor solution for all aspects of turbine automation

within the plant automation platform.

The SD Series uses ABB’s extensive set of field- proven standard function code algorithms and

S+ Engineering’s graphical design tools to develop control strategies. By using the same

function code algorithms as previous generation Harmony and INFI 90 rack controllers,

the SD Series supports easy and risk-free reuse of time-tested, field-proven control application

solutions.

All-in-all, SD Series products provide users with the benefits of fast, accurate and uninterrupted

control of their process at the lowest design, installation, and operation cost.

S+ Operations, S+ Engineering and other applications communicate with SD Series

Control and I/O over the flexible high-speed, high-throughput and high-security 100 Mbps

Fast Ethernet-based redundant communications Plant Network (PN800). The network-centric

architecture allows for integration of field devices, process and electrical system areas

and business enterprise systems in a SIMPLE,SCALABLE, SEAMLESS, SECURE manner.
