Technical Specifications Model: DO802 System Compatibility: ABB S800 I/O, AC800M Controller Output Channel Quantity: 16 channels Output Type: 24 V DC sourcing transistor output Per‑channel Output Current: Maximum 0.5 A Isolation Structure: Two groups of 8‑channel galvanic isolation Logic Power: Supplied by S800 rack backplane Field Power: External 24 V DC 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 Sixteen‑channel sourcing‑type 24 V DC transistor outputs adapt to field‑side sinking‑type loads. Two‑group galvanic isolation prevents field surge disturbance from invading control logic circuit. Built‑in per‑channel over‑current and short‑circuit hardware protection. Front‑panel LED indicators display real‑time working status for each output channel. Integrated self‑diagnosis function detects power supply abnormality, channel fault and internal hardware error. Supports hot‑swap operation within S800 system maintenance permission scope.
Application Scenarios S800 I/O DO802 spare‑part replacement work. Industrial automation cabinet sourcing‑type discrete output control for solenoid valves and relays. Water‑treatment, building auxiliary control and general‑purpose process on‑off control projects.
Installation Requirements Insert DO802 into S800 I/O rack target slot and lock side spring buckle. Connect external 24 V DC field power and field load cables to front‑side screw terminals, tighten terminals to specified torque. Implement protective earthing complying with S800 system grounding specification. Separate field power output cables from weak‑signal control cables inside cabinet. Reserve ventilation heat‑dissipation space around module slot. Ambient operating temperature shall keep within 0 ℃ ~ +55 ℃ without condensation.
