Product Overview

• PN: DO801
• Official part number: 3BSE020510R1
• Brand: ABB
• Series: S800 Distributed I/O System
• Type: Digital Output Module

• Function: Standard switch output expansion card for S800 I/O station. It receives control instructions from AC800M controller, converts internal bus signals into 24VDC sourcing switch signals to drive solenoid valves, DC relays, indicator lamps and small actuators on site. It realizes on-off logic execution and equipment action control, and adopts group isolation design to avoid interference caused by field ground potential difference. It supports preset safe output state when communication fails to prevent misoperation of field equipment.

Core Features

• 16 output channels integrated into one isolation group, each channel equipped with independent overcurrent, short-circuit and overtemperature electronic protection
• High-side source type transistor output, output voltage range 10~30VDC, single channel continuous load current 0.5A
• Built-in freewheeling suppression circuit for inductive loads to absorb back electromotive force and extend module service life
• LED status indicator for each channel to directly display output on/off state for quick on-site troubleshooting
• Supports OSP preset output state function; automatically locks outputs to predefined safety mode once communication with controller is interrupted
• PCB conformal coating process, dustproof, moistureproof and anti-electromagnetic interference, adapting to long-term cabinet operation
• Standard side bus docking with main controller and other I/O modules, supports hot swapping under redundant rack power supply without system shutdown

• Detachable terminal connector design for convenient wiring and module replacement without modifying field cables
