Designed for maximum reliability and availability

SD Series controller subsystems are redundant at all levels – CPU, power, internal bus, I/O networks,

communication ports and plant network.

Compliance with international standards assures the highest level of reliability and quality needed

to meet the most rigorous global specifications and requirements. Together, they provide users

with fast, accurate, uninterrupted control of their process.

Further, SD Series controllers are designed to specifically address cybersecurity threats as

defined by the industry leading standard IEC 62443. For example, SD Series controllers are

ISA Secure Component Security Assurance (CSA) certified (formally known as Embedded Device

Security Assurance, EDSA).

SD Series controllers are the latest in a long line of ABB field-proven process controllers and

can adapt to a broad spectrum of applications and process requirements. Configured by S+

Engineering, SD Series controllers feature an extensive library of predefined function codes

for easy building block design of complex control strategies to fit any control application,

including continuous, sequential, batch and advanced control.
