The ABB DO820 (3BSE008514R1) is a high-performance digital output module designed for the S800 I/O system. This module features 8 individually galvanically isolated relay output channels, providing flexible control for a wide range of industrial applications requiring signal switching up to 230 V AC/DC.

Features

  • 8 individually galvanically isolated relay channels
  • Supports switching voltages from 24 V to 230 V AC/DC
  • Rated for 3 A output current per channel
  • Compact S800 I/O form factor for high-density rack mounting
  • Low power dissipation (typical 2.9 W)

Installation Guidelines

  • Ensure the system power is disconnected before installing or removing the module from the S800 I/O base unit.
  • The module is designed for mounting on an S800 I/O DIN rail-based cluster. Ensure proper mechanical seating to engage the Modulebus connection.
  • Verify that field wiring is routed according to site standards, keeping high-voltage relay circuits separate from sensitive low-voltage signal cabling to prevent EMI.
  • Maintain adequate spacing within the cabinet to allow for proper airflow and cooling, as the module dissipates heat during operation.
  • Observe the 600-meter maximum field cable length limit to maintain signal integrity.

FAQ

What is the primary function of the ABB DO820?
The DO820 is a digital output module used to interface the control system with field devices using relay-based switching, providing electrical isolation between the control logic and the field load.

Are the channels on the DO820 isolated?
Yes, the DO820 features 8 individually galvanically isolated relay output channels, which helps prevent ground loops and protects the control system from field-side electrical faults.
