ABB DO801

Product Brief:​ The DO801 is an S800 I/O digital output module providing sixteen 24 V DC sourcing (PNP) transistor outputs grouped in two isolated groups of eight. Each channel is current-limited and protected against short-circuit and over-temperature. It drives 24 V DC final control elements such as solenoid valves, indicator lights, and small contactor coils in process automation systems.

Description

ABB DO801

  • Technical Specifications:
    • Output Voltage: 24 V DC (12–32 V DC range; nominal 24 V)
    • Channels: 16, in 2 isolated groups of 8
    • Output Type: High-side MOSFET, current sourcing (PNP)
    • Max Continuous Current: 0.5 A per channel; total per group limited by thermal design
    • On-State Voltage Drop: <0.5 V typical
    • Short-Circuit Protection: Current-limited; automatic recovery
    • Isolation: Group-wise isolated from ModuleBus (500 V AC dielectric, 50 V rated)
    • Process Voltage Supervision: One supervision input per group; error reported on loss
    • 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)
    • MTU Compatibility: TU810, TU812, TU814, TU830, TU833, TU842, TU843, TU852
    • Certifications: CE, UL/cUL, ATEX Zone 2, cULus, marine (ABS, BV, DNV, LR)
  • Functional Features / Application / Structure / Working Principle / Precautions:​ Essentially same as DO810 below but with 16 outputs (vs DO810 also 16 — DO801 is earlier-generation, same electrical spec, slightly different key code on some MTUs). Refer to DO810 detail for operational notes. Key difference: DO801 older generation; DO810 adds OSP (Output Set to Predetermined state on error/comm loss) as standard — check project requirement.
