ABB DSDI110 Digital Input Board for Symphony Plus

ABB DSDI110 Digital Input Board for Symphony PlusProduct Overview The ABB DSDI110 serves as a high density digital input interface for the Advant OCS and Symphony Plus control platforms. This 32 channel board captures discrete signals from field devices, including limit switches, pushbuttons, and relay contacts. By converting 24V DC field voltages into logic level data for the system bus, the DSDI110 enables real time monitoring of industrial processes in power plants, refineries, and manufacturing

the AAT141-S50 prevents ground loops and eliminates common-mode interference

mA) matches the hardware settings and the corresponding Termination Assembly (TA) capabilities

Galvanic isolation is a mechanical necessity for protecting sensitive DCS logic from high-voltage transients on the field side

54 A @ 5V DC

and Active (non-contact) Speed Sensors

It is a fundamental component for plants utilizing older 3300 racks that require robust

shielding internal monitoring modules from high-frequency electromagnetic interference (EMI) common in power generation and motor control centers

reducing the need for multiple expansion enclosures

we recommend periodic inspection of the 51400918-100 cover for dust accumulation to ensure unobstructed airflow and optimal cooling performance
