Introducing the Symphony Plus SD Series, the energy-efficient automation solution

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

In most industries today, energy consumption represents a very significant operating expense in the production process. So reducing energy consumption leads directly to improved bottom line profits. Even in less energy-intensive industries, improvements in energy efficiency help maintain competitive advantages. For power
producers, between 4 and 15 percent of a power plant`s entire output is used to power auxiliary systems, from water treatment, fuel preparation, and environmental systems to lighting and air conditioning.

Without these systems, the plant can’t run, but every watt of electricity saved by improving energy efficiency can be sold to generate higher revenues or lower fuel
consumption to reduce operating costs. 

Symphony Plus SD Series 

Introducing ABB’s Symphony® Plus SD Series, a flexible and scalable portfolio of control and I/O products that are designed to improve efficiency and productivity in diverse operating environments within the power and water industries. 

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.

The SD Series 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, highdensity design and streamlined architecture that reduce control and I/O hardware requirements and cabinet footprint, thus lowering design, installation and operating costs. It 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 the use of parts that can affect reliability and productivity, thereby reducing footprint and lowering installation costs. These features 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 highperformance and highly reliable controllers and control loop integration of secondary
smart field device. 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 fieldproven solutions and avoiding rip and replace alternatives.

SD Series products

SD Series is a suite of flexible control and I/O products that work across the entire control landscape, providing total plant automation regardless of application type, size or
location. The suite includes a set of highperformance, scalable process controllers that support the plant’s total control requirements, from discrete and continuous to batch and advanced control applications. Supported by a comprehensive range of I/O options, SD Series delivers powerful, versatile and scalable automation solutions for plant applications of all sizes and requirements.

The SD Series portfolio comprises:
