ABB HIES308461R Water-Cooled Resistor

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.

Specifically, SD Series solutions:

• Use the extensive set of field-proven INFI 90 function code algorithms as previous generation controllers

• Use traditional INFI-Net exception reporting over redundant 100 Mbps Fast-Ethernet (PN800)

• Extend current Composer graphical design engineering tools with device management

capabilities

Further, Symphony Plus Rack and SD Series control networks, INFI-Net and PN800

respectively, can be connected via a self-configuring INFI-Net to Ethernet bridge

(IEB800) module (Figure 08). Use of this bridge makes resident data on either network available

for use in control applications, or for display in the other system.
