Technical Specifications Model: DSDO115K12, Part No. 3BSE019933R1 System Compatibility: ABB Advant Master DCS System Output Channel Quantity: 12 channels Output Type: Transistor output Rated Output Signal: 24 V DC Per‑channel Maximum Current: 0.5 A Galvanic Isolation: Group‑wise isolation Power Supply: Supplied by rack backplane Mounting: Eurocard rack plug‑in Operating Temperature: 0 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Protection Class: IP20 Certifications: CE
Functional Features Twelve independent 24 V DC transistor output channels realize multi‑point discrete on‑off control. Group‑wise galvanic isolation blocks field surge interference from invading control logic circuit. Per‑channel over‑current and short‑circuit hardware protection prevents module damage under field fault conditions. Front‑panel LED indicators display real‑time output status for each channel. Built‑in comprehensive self‑diagnosis detects backplane power failure, bus communication error and internal hardware faults. Supports hot‑swap operation under authorized Advant Master system maintenance procedures.
Application Scenarios Spare‑part replacement for Advant Master DSDO115K12 3BSE019933R1 module. Discrete output control for chemical, pulp and paper legacy DCS cabinets. On‑off driving for field intermediate relays, status indication lamps and small‑size solenoid valves.
Installation Requirements Insert DSDO115K12 3BSE019933R1 fully into target rack slot and tighten front locking screw. Connect external 24 V DC field power and field load cables to front screw terminals, tighten terminals to specified torque value. Complete protective earthing following Advant Master system grounding specification. Separate field output power cables from weak‑signal analog cables inside control cabinet. Reserve sufficient ventilation space around module slot for heat dissipation.
Usage Notes Each channel load current cannot exceed rated maximum value 0.5 A. Inductive loads shall be equipped with external free‑wheel arc‑suppression components.
