ABB DO810

Product Brief:​ The DO810 is a standard S800 I/O 24 V DC digital output module with sixteen sourcing (PNP) transistor outputs in two isolated groups of eight. It features process voltage supervision per group and OSP functionality — outputs can be forced to a predefined safe state (OFF or ON) on communication error or module fault. Short-circuit and over-temperature protected.

Description

ABB DO810

  • Technical Specifications:
    • Output Voltage: 24 V DC (12–32 V DC operating range; nominal 24 V)
    • Channels: 16, 2 groups × 8 ch
    • Output Type: High-side MOSFET, current sourcing (PNP)
    • Max Current: 0.5 A per channel continuous; group thermal limit applies
    • On-State Drop: <0.4 Ω (typ. <0.5 V @ 0.5 A)
    • Short-Circuit Protection: Current-limited; auto-recovery after fault clears
    • OSP (Output Set to Predetermined state): Configurable per channel/group — last state, 0, or 1 on error/comm loss
    • Process Voltage Supervision: One sense input per group; module warning/fault if process voltage absent
    • Isolation: Group isolated from ModuleBus (500 V AC test, 50 V rated)
    • Power Dissipation: Typ. 2.1 W (all outputs ON @ 0.5 A)
    • ModuleBus Current: +5 V typ. 80 mA
    • Max Field Cable Length: 600 m
    • Operating Temp.: 0 °C to +55 °C (compact MTU vertical: max +40 °C)
    • Compatible MTUs: TU810, TU812, TU814, TU830, TU833, TU842, TU843, TU852
    • Keying Code: AA (verify against MTU key setting)
    • Certifications: CE, UL/cUL, ATEX Zone 2, cULus, marine
  • Functional Features:
    • OSP ensures defined fail-safe behavior on communication loss or module fault
    • Per-channel status LED + module Run/Fault/Warning/OSP LEDs
    • Inductive load suppression (built-in free-wheeling diode equivalent in output stage)
    • Open-load / short-circuit detection reported to controller
    • Hot-swap capable when used with hot-swap-enabled MTU
  • Application / Material / Structure / Working Principle:​ Same as DO801 — key differentiator is OSP and newer generation diagnostics.
  • Installation Requirements:
    • Insert into S800 MTU ensuring key matches (AA); tighten module retaining screw
    • Connect 24 V DC process supply to group-common terminals; 0 V to ZP/common
    • Configure OSP behavior in engineering software before commissioning
    • Wire field device between output terminal (+) and 0 V return
  • Precautions:
    • Verify total group current does not exceed thermal derating — at >55 °C ambient or compact MTU, reduce load
    • For solenoid valves with LED indicator, ensure LED current + coil current ≤0.5 A
    • If OSP = “Off on error”, confirm this is the desired safety action — some processes require “last state” or “On”
    • Do NOT mix sourcing (PNP) and sinking (NPN) wiring on same module
