SD (Symphony DIN) Series I/O is Symphony Plus flexible and modular I/O offering that works across the entire control landscape regardless of application type, size, or physical location. It includes traditional analog, HART, and digital modules as also turbine specific modules for integrated turbine control solutions.

I/O Systems - SD Series I/O
ABB Ability™ Symphony® Plus Hardware Selector
The SD Series I/O product family includes DIN Rail horizontally or vertically mounted digital and analog modules, as well as integration with intelligent field devices and protocols. Hardwire I/O and Fieldbus I/O coexist and use the same function block library to build real-time control applications.
Traditional SD Series analog input modules interface with field inputs such as pressure and flow transmitter signals, thermocouple inputs, and resistive temperature device (RTD) inputs. Analog output modules provide output signals to adjust final control elements such as control valves, positioners, actuators, etc. SD Series digital input modules have input channels to read the states of switches, relay contacts, solenoids, etc. Digital output modules provide output channels for DC or AC switching applications.
The digital outputs can be used to drive annunciators and to drive two-state final control elements such as actuators, relays, and solenoids. For SD Series Digital I/O, each channel can be individually configured as an SOE (Sequence of Events) point. This flexibility removes the cost and complexity of assigning additional digital inputs as SOE in the field. SOE with 1 msec timestamp is available across the entire system, whether the I/O is local or remotely located.
Below is an outline of the range of different SD I/O modules available.
