ABB SD Series Comprehensive I/O product portfolio
SD Series
Comprehensive I/O product portfolio
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 using
PROFIBUS DP, HART, IEC 61850. IEC 60870-5 104. DNP 3.0. and Modbus TCP communications.
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.
