Symphony® Plus SDe Controllers (SPC) are the next generation of time-tested, field-proven SD series controllers. Specifically designed for the evolution, enhancement, and expansion of Harmony Rack (HR) systems, SDe controllers provide flexible, mounting options that allow them to be installed in multiple configurations. In every form, the controllers are form, fit, and functional replacements for HR controllers. Offering complete scalability, the powerful controllers are suitable for small to large applications.
The controllers belong to the ABB Ability Symphony Plus Control and I/O family: the SDe Series – a green portfolio of completely scalable control and I/O products that deliver a total plant automation solution for your process regardless of application type, size, or physical setting. Energy efficient, compact, and providing digital infrastructure to integrate smart field devices seamlessly makes SDe Series the best automation solution for your new installation, upgrade, or expansion.
SDe 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, SDe 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.
SDe 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, SDe Series controllers are designed to specifically address cybersecurity threats as defined by the industry-leading standard IEC 62443. For example, SDe Series controllers are ISA Secure Component Security Assurance (CSA) certified (formally known as Embedded Device Security Assurance, EDSA).
Below is an outline of the range of different SDe Controllers available.
