Technical Specifications

The ABB DSAX 110A 3BSE018291R1 Analog Input / Output Board belongs to ABB Advant OCS series distributed control system spare parts, manufactured in Switzerland. This integrated analog input and output composite board is developed for Advant OCS DCS rack control system, serving as a comprehensive analog signal processing unit inside control cabinets. It integrates analog signal acquisition and analog regulation output functions, which can collect continuous analog measuring signals from field transmitters such as temperature, pressure and flow, and convert digital control commands from main controller into standard analog driving signals to drive on-site regulating valves, actuators and frequency converters, realizing one-board measurement and adjustment for independent small production process loops.

Troubleshooting & Comissioning Checklist

Insert Module: Guide the module firmly into its designated rack slot until the faceplate latching mechanism locks into place.
Observe LED Init Cycle: Watch the front status LEDs immediately upon seating; the green Run LED should steady, while any red Fault LED must clear after internal diagnostics finish.
Input Loop Checks: Apply a fixed signal at the connection unit terminals and verify that the Engineering Value reads 50% in the controller database.

Technical FAQ

Q: What is the exact function of the DSAX110A?
A: It acts as a dual-purpose signal processing interface between field devices (like sensors, flowmeters, and control valves) and the central processing unit of your Distributed Control System (DCS). It translates real-world analog physical measurements into 16-bit digital values for the PLC, and vice versa for field actuators.

Q: Does this module support redundant configuration layouts?
A: Yes. You can connect two DSAX110A modules to the same connection unit to build a redundant system. When configured for redundancy, the system application programmer manages the duplicate signal paths exactly like standard inputs and outputs to ensure seamless fault-tolerance.

Q: How do I handle diagnostic or channel-fault issues?
A: If a channel fails, check the system status LEDs on the front faceplate of the S100 rack module. Check if the fault is localized to an individual 4-20mA current loop or if it impacts the whole board. Ensure the external power distribution to the connection unit is stable, and inspect the interface ribbon cable for secure physical seated placement.

Q: Do you supply brand-new, original parts or second-hand refurbished items?

A: Our stock consists of Original New items; all products undergo quality inspection to ensure they are fully functional.

Q: What guarantees are included with the shipment?
A: All items in stock are tested by engineers, packed in professional ESD packaging, and shipped via express logistics with a global delivery time of 24–48 hours.

Q: How long does global shipping take?
A: Stock items are typically dispatched within 24 hours. Shipments are sent via DHL or FedEx Express, taking approximately 3–5 days to reach Asia, 4–6 days to Europe and the Middle East, and usually arriving within a week in major industrial regions worldwide.

Q: If the model I need is not listed on the website, can I request a quote?
A: Yes. We hold over 200,000 SKUs of industrial spare parts in stock, and many long-tail models are not listed in full. You can send us an RFQ (Request for Quote) directly, and we will provide wholesale pricing promptly.
