Process Automation I/O Solution – ABB DX910S | S900 Series D-63754
Where This Product Is Used
The ABB DX910S is a Digital I/O Module within the S900 Remote I/O system, purpose-built for process industries operating in hazardous and non-hazardous environments. Engineers specify this module across a wide range of critical applications:
- Oil & Gas Upstream/Downstream: Wellhead control panels, separator skids, and pipeline SCADA systems requiring certified remote I/O in Zone 1/Zone 2 hazardous areas.
- Chemical & Petrochemical Plants: Reactor monitoring, valve position feedback, and interlock logic in distributed control architectures.
- Power Generation: Turbine control auxiliaries, switchgear status monitoring, and BOP (Balance of Plant) I/O expansion.
- Water & Wastewater Treatment: Pump station automation, level switch monitoring, and remote telemetry outstations.
- Pharmaceutical Manufacturing: Clean-room process control with deterministic digital signal handling.
- Marine & Offshore Platforms: Topside automation where compact, certified I/O is mandatory.

Application-Specific FAQ
Q: Can the DX910S be used in Zone 0 hazardous areas?
A: No. The S900 system is certified for Zone 1 and Zone 2. Zone 0 applications require intrinsically safe barriers and a different I/O architecture.
Q: Is the DX910S compatible with non-ABB DCS platforms?
A: Yes. Via PROFIBUS DP, the S900 coupler can interface with Siemens, Honeywell, Yokogawa, and other DCS platforms that support standard PROFIBUS DP slaves.
Q: What is the difference between DX910S and other S900 digital modules?
A: The DX910S provides combined digital input and output channels. Other variants (e.g., DI910S, DO910S) are dedicated input-only or output-only. Consult the ABB S900 system manual for channel count and signal specifications.
Q: Can I mix DX910S with analog modules on the same S900 node?
A: Yes. The S900 system supports mixed digital and analog modules on a single fieldbus coupler node, up to the maximum module count per coupler.
Q: Do you provide an ABB factory warranty?
A: New-in-box units carry the original ABB manufacturer warranty. Refurbished units carry a Konmask 90-day functional warranty. Details provided at quotation.
