Technical Specifications Model: DO810, Part No. 3BSE008510R1 System Compatibility: ABB S800 I/O, AC800M Controller Output Channel Quantity: 8 relay output channels Output Form: Form A normally‑open relay dry contact Per‑contact Rating: 250 V AC 2 A, 30 V DC 2 A Galvanic Isolation: Channel‑to‑logic side isolation 1500 V AC Logic Power Supply: From S800 rack backplane Mounting: DIN‑rail S800 rack plug‑in Operating Temperature: 0 ℃ to +55 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Protection Class: IP20 Certifications: CE, UL
Functional Features Eight independent mechanical relay dry‑contact outputs support both AC and DC field loads. Complete galvanic isolation between control logic circuit and field load circuit. Each channel front‑panel LED indicator displays relay actuation status. Built‑in module self‑diagnosis monitors logic power supply and communication status. No field power supplied by module, field load power is fully external‑provided. Supports hot‑swap under authorized S800 system maintenance conditions.
Application Scenarios S800 I/O DO810 3BSE008510R1 module spare‑part replacement. Process automation cabinet interlock relay output, high‑voltage auxiliary contact signal output. Industrial occasions requiring dry‑contact relay output for multi‑voltage‑level load control.
Installation Requirements Insert DO810 (3BSE008510R1) into S800 I/O rack target slot and lock side spring buckle. Connect external field load power cables and load equipment to front‑side relay contact screw terminals, tighten terminals to specified torque. Implement protective earthing complying with S800 system grounding specification. Separate high‑voltage field load cables from weak‑signal control cables inside control cabinet. Reserve ventilation heat‑dissipation space around module slot. Ambient operating temperature shall keep within 0 ℃ ~ +55 ℃ without condensation.
