ABB DO810 (3BSE008510R1) – 16‑Channel 24 VDC Digital Output Module for S800 I/O Systems

The ABB DO810 is a reliable 16‑channel 24 VDC digital output module designed for S800 I/O installations. From my experience, it fits best when you need compact, sourcing (PNP) transistor outputs with built‑in protection and straightforward diagnostics. You might notice that it slots into existing S800 racks without fuss, keeping cabinet space tight and wiring tidy—especially in brownfield upgrades where downtime needs to be minimal.

Key Features

• 16 sourcing outputs, 24 VDC – Typical PNP transistor outputs for direct driving of solenoids, contactors (via interposing relays), beacons, and valves.
• Two isolated output groups (2 × 8) – Separate field power per group helps segment loads and reduce fault propagation.
• Per‑channel protection – Short‑circuit and thermal protection on channels improve uptime in most cases.
• Channel and module diagnostics – Status LEDs simplify commissioning and troubleshooting on the panel door.
• S800 ModuleBus integration – Seamless with ABB AC 800M–based systems via standard S800 terminal bases.
• Compact, cabinet‑friendly – Single‑width S800 form factor typically saves rail space and makes wiring cleaner.
• Compatible base units – Works with TU8xx terminal bases (e.g., TU810/TU812), which many sites already stock.

Technical Specifications

Application Fields

The DO810 fits discrete and hybrid automation where reliable 24 VDC actuation is standard. Typical uses include:

• Process industries: chemical, water/wastewater, power balance‑of‑plant—driving valves, blowers, and dampers through interposing relays.
• Factory automation: packaging lines, conveyors, and machine safety indicators where fast transistor outputs are preferred.
• Oil & gas and utilities: remote I/O cabinets where cabinet footprint and ease of maintenance matter.
• Material handling: stack lights, solenoid brakes, clutch control, and diverter gates.

One maintenance manager told us they swapped aging relay boards for DO810s “section by section” and appreciated the two group power feeds—it let them isolate a troublesome zone without impacting the whole line.

Advantages & Value

• Reliability – Solid‑state outputs with integrated protection reduce nuisance trips and avoid relay wear.
• Compatibility – Native to S800 I/O; typically plug‑and‑play with TU8xx bases already in service.
• Lifecycle cost – Lower maintenance versus relays; simplified spares since one module covers many 24 VDC loads.
• Support – Field‑proven in many ABB DCS/PLC builds; documentation and spare availability are strong.

Installation & Maintenance

• Cabinet & mounting – Install on DIN rail with TU8xx base; allow ventilation and keep within 0…+55 °C ambient.
• Wiring – Use separate 24 VDC field supplies for each group (2 × 8). Keep commons and returns consistent to avoid ground loops.
• Protection – Size external fusing per load; although channels are protected, correct upstream protection improves selectivity.
• Commissioning – Verify outputs with the on‑module LEDs and your DCS/PLC force tools before energizing final elements.
• Routine care – Periodic terminal re‑torque, dust cleaning, and firmware updates on the controller interface where applicable.

From my experience, keeping high‑inductive loads behind interposing relays extends module life and makes troubleshooting simpler when contact wear is expected.
