Keterangan
The ABB DO810 (3BSE008510R1) is a 16-channel digital output module designed for the S800 I/O system. This module provides reliable control for field devices such as contactors, relays, and indicator lamps. It features two isolated groups of eight channels, each equipped with process voltage supervision to ensure system integrity and diagnostics.
Features
- 16 digital output channels (24 V DC, current sourcing).
- Two isolated groups of 8 channels with independent process voltage monitoring.
- Integrated Output Set to Predetermined state (OSP) functionality for safe-state management during communication loss.
- Comprehensive protection including short-circuit, over-temperature, and over-voltage monitoring.
- Optical isolation barrier between field and system side.
- LED status indicators for individual output channel monitoring.
Applications
-
Burner Management Systems: Sequencing fuel valves and ignition hardware.
-
Motor Control: Managing start/stop logic for large motor starters and pump sequences.
-
Turbine Auxiliaries: Controlling hydraulic pumps, cooling fans, and valve actuators.
-
Substation Automation: Interfacing with circuit breakers and isolators.

Installation Guidelines
- Ensure the power supply is disconnected before installing or removing the module from the ModuleBus.
- Mount the module in a clean, dry environment within an appropriately rated industrial enclosure to protect against dust and moisture.
- Ensure proper grounding of the S800 I/O station to minimize electromagnetic interference (EMI).
- Maintain adequate ventilation clearance around the module to prevent overheating during operation.
- Use shielded cables for field wiring to ensure signal integrity and compliance with EMC standards.
- Handle with standard ESD (Electrostatic Discharge) precautions to prevent damage to internal circuitry.
FAQ
What does the OSP function do on the DO810?
The Output Set to Predetermined (OSP) function allows the module to force outputs into a pre-configured safe state if a communication error occurs or if the watchdog timer expires, preventing uncontrolled operation of field equipment.
Are the channels in the DO810 isolated?
Yes, the 16 channels are divided into two isolated groups of eight. Each group features its own supervision input that reports process voltage status via the ModuleBus.
Can this module drive inductive loads?
The DO810 includes built-in inductive load suppression components, allowing it to drive standard industrial relays and solenoids directly.
