Introducing the new Symphony Plus SD Series

Green automation solution reduces energy consumption, lowers hardware requirements and withstands extreme operating conditions.

The SD Series is the latest addition to the Symphony® Plus S+ Control and I/O family. This family, which also includes the HR Series (Harmony Rack) and MR Series (Melody Rack), provides Symphony Plus with a comprehensive offering to meet the needs of new and existing customers from all segments and all regions.

Originally introduced in March 2012, with subsequent portfolio enhancements in 2014 and 2015, the SD Series is designed for distributed applications in conventional and renewable power plants and water networks. It features modular DIN rail packaging; a flexible, Fast Ethernet-based plant network; intelligent electrical and field device integration; PROFIBUS, HART, IEC 61850 and Modbus TCP communication protocols; and an integrated turbine control solution. The SD Series also protects investments made in previous controllers, while delivering higher performance, reliability and capacity.

SD Series products have a modular, high-density design and streamlined architecture that reduce control and I/O hardware requirements and cabinet footprint, thus lowering design, installation and operating costs. The SD Series is a green automation solution that provides significant energy
savings with low 24 VDC power consumption and lead-free RoHS-certified modules.

SD Series products are designed to withstand extreme environmental conditions, which makes them ideal for remote I/O applications. Their G3 coating and 70 °C temperature rating eliminate the need for fans, louvers, air filters, purging systems, or other environment controlling techniques.

Significantly higher efficiency means lower power consumption, less heat dissipation requirements, and less need for cooling systems. This eliminates theuse of parts that can affect reliability and productivity,  thereby reducing footprint and lowering installation costs. This can make a huge difference in installation expenditure by reducing the need for climate-controlled buildings or cabinets. Once in operation, the reduced volume of parts and equipment improves reliability and cuts maintenance costs.

The SD Series maximizes uptime and production with a scalable family of high-performance and highly reliable controllers and control loop integration of secondary smart field device information. 

They protect intellectual investment in existing INFI 90 / Harmony systems - one of the most widely used control systems in power generation worldwide - by enabling the easy reuse of existing INFI 90 control strategies.

Backwards and forwards compatibility ensures smooth integration with existing and future systems, enabling customers to protect previous investments by reusing field-proven solutions and avoiding rip and replace alternatives.
