Product Introduction & Supply Chain Strategy
The ABB DASO110 provides 4 galvanically isolated analog outputs for S800 I/O systems in ABB 800xA DCS, driving control valves, VFDs, and actuators with 0-20 mA or 0-10 V signals. It delivers precise setpoint transmission for flow, pressure, and position loops in continuous process industries with fault detection for loop integrity.
New Surplus stocking cuts lead time variability for this fast-moving spare, reducing TCO versus OEM by 30-50% while eliminating refurbished risks like output drift causing valve oscillations and process instability. JIT replenishment with min/max 1/3 levels; 1-2 year warranty standard.
Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
Lock out/tag out I/O rack. ESD strap required. Document field wiring polarity (+/–), loop resistance (<600 Ω), HART loads if present. Verify MTU810/830 terminal assignments; confirm 24 V loop power buffer.
Stage 2: Removal
Disconnect field wiring from MTU terminals. Release Modulebus latch; extract straight. Inspect gold pins for wear.
Stage 3: Installation (Clone & Seat)
Replicate wiring per photos to MTU screw terminals (1-4 channels). Seat firmly into Modulebus slot; latch securely. No configuration jumpers needed.
Stage 4: Power-On & Testing
Power rack; verify RUN LED green, no Fault. Command 4-20 mA ramp via 800xA; measure output accuracy (±0.05%), test short/open diagnostics.
Firmware/Software Versions & Upgrade Notes
Hardware-configured via Control Builder A; no module firmware. Compatible with PM86x controllers V5.1+, S800 Firmware R1.x+.
Mismatches trigger output freeze; verify MTU firmware match pre-swap. Recalibrate loops post-install; hot-swap supported on redundant bus.
Frequently Asked Questions (FAQ)
Confirmed New Surplus quality?
Yes—factory sealed with verified isolation test, zero drift hours. Avoids refurbished calibration loss causing 0.5% setpoint errors.
Price positioning vs OEM/refurb?
Vendor frame agreements yield 30-50% off list for tested New Surplus; beats used modules with intermittent open-circuit faults.
EOL concerns for DASO110?
Active S800 production; JIT via preferred suppliers. Stock min 1/max 3 for critical loops
Hot-swappable design?
Yes on live CEX bus—redundant Modulebus prevents single-point failure. Confirm no field shorts first.
Calibration transfer on replacement?
Scaling stored in 800xA database; module plug-and-play. Validate loop response post-swap.
