PRODUCT INFORMATION
Product Overview
The ABB DSDI 110A 57160001-AAA is a 32-channel digital input module for the Advant OCS S100 I/O system. This board processes 24 VDC binary field signals across automation and process control architectures. Channels configure for cyclic scanning routines or interrupt-driven signal acquisition depending on system needs.
When paired with the DSTD 150A connection unit, the board divides into four isolated groups of eight channels. Alternatively, pairing with a DSTD 190 unit and DSTK 221L3 cable enables sequence-of-events recording. That configuration provides hardware pulse extension and 1 ms time tagging resolution for critical events. Typical internal 5 V bus current draw is 460 mA during normal operation.

PRODUCT FAQ
Frequently Asked Questions
What termination units work with the ABB DSDI 110A module?
The DSDI 110A connects to the DSTD 150A screw-terminal unit for standard inputs. It connects to the DSTD 190 unit using a DSTK 221L3 cable for time tagging.
What is the time-tagging resolution of the DSDI 110A?
The module provides 1 ms event time tagging resolution. This function requires the DSTD 190 input set configuration.
What are the input voltage thresholds for 24 VDC operation with DSTD 150A?
A logic-one input requires 15 to 35 VDC. A logic-zero state corresponds to -25 to +5 VDC. Input impedance is 4 kΩ.
How is pricing and quotation handled for the 57160001-AAA board?
Final quotation depends on condition, current stock, destination, and delivery requirements. Published market values serve as an indicative market reference only and are not a final quotation.
