The Symphony® Plus SDe Control and I/O series builds off the success of the

Symphony® Plus SD series to provide an even greener, energy-efficient portfolio

of scalable control and I/O products. The suite features modular, compact packaging,

a modern industrial standard ethernet communications backbone, utilizes the same

field-proven control logic algorithms as previous generation SD and HR controllers.

Key principles behind the SDe Series hardware are focused on the evolution,

enhancement, and expansion of existing HR and Symphony DIN (SD) systems.

For Harmony rack installations, the SDe

series provides increased modularity, enhanced functionality, 1-to-1 module replacements,

and space fit mounting options for seamless evolution.

Full compatibility with the SD series allows SD systems

to be expanded using the latest technology, while preserving investments made in controllers,

I/O hardware and software, and delivering higher performance, reliability, and capacity.
