Technical Specifications Model: DO910 System Compatibility: ABB Advant Master, S800 extended I/O Output Channel Quantity: 8 relay output channels Output Form: Form A normally‑open dry contact Per‑contact Rating: 250 V AC 3 A, 30 V DC 3 A Galvanic Isolation: 1500 V AC between logic side and field side Logic Power Supply: From system rack backplane Mounting: Rack plug‑in module Operating Temperature: 0 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Protection Class: IP20 Certifications: CE
Functional Features Eight independent mechanical relay dry‑contact outputs adapt to multi‑voltage‑level field load switching. Complete galvanic isolation separates control logic circuit from field‑side load circuit. Per‑channel front‑panel LED indicator reflects relay actuation real‑time status. Built‑in module self‑diagnosis monitors backplane power‑supply and internal communication status. Field‑side load power is fully externally supplied, independent of module internal power circuit. Supports hot‑swap under permitted system maintenance workflow.
Application Scenarios DO910 module spare‑part replacement for Advant Master and S800 extended I/O system. Legacy process automation cabinet interlock output, auxiliary equipment on‑off control. Industrial projects requiring multi‑voltage dry‑contact relay output control.
Installation Requirements Insert DO910 module into designated rack slot and fasten edge locking buckle. Connect external field load power and load equipment cables to front‑side relay‑contact screw terminals, tighten terminals to specified torque. Implement protective earthing complying with host control system grounding specification. Separate field high‑voltage load cables from weak‑signal control cables inside cabinet. Reserve ventilation heat‑dissipation space around module slot. Ambient operating temperature shall keep within 0 ℃ ~ +60 ℃ without condensation.
Usage Notes Field application shall not exceed rated voltage and current limits of relay contacts.
