The DO818 3BSE069053R1 is a 32-channel, 24V DC digital output module for the S800 I/O system, featuring two electrically isolated groups of 16 channels, each supporting 0.5A continuous output.
32channels for 24 v d.c.
Two 16-channel isolated groups (RIV5oV) each with process voltage supervision
12-32V DC range (24V DC nominal) with 0.5A maximum continuous current per channel
As a mature and core component of the Distributed Control System (DCS), the ABB DO818 (3BSE069053R1) seamlessly integrates into mainstream industrial automation architectures, such as ABB Ability System 800xA or the Compact Product Suite. Through its highly efficient ModuleBus interface, the module maintains high-speed, real-time bidirectional data communication with upper-level controllers (such as the AC 800M), enabling the precise execution of complex logic control commands with millisecond-level response times. For physical deployment, the DO818 utilizes a highly flexible modular design that must be paired with Modular Terminal Units (MTUs) like the TU818, TU819, or TU830. This setup not only ensures neatly organized field wiring for 2-wire or 3-wire field devices but also fully supports hot swap functionality across its entire lifecycle.

Oil & Gas
Used for the batch open/close control of motorized/solenoid valves in long-distance pipelines and refineries, as well as driving safety alarm indicator lights in the central control room.
Power Generation
In coal-fired or gas-fired power units, it is used to control auxiliary relay closing, circuit breaker tripping, and interlock trip indications for boiler and steam turbine systems.
Pharmaceuticals
In GMP-compliant fermenter and reactor systems, it centrally controls sterile valve switching and fluid path transitions for Clean-in-Place (CIP) and Sterilize-in-Place (SIP) systems.
Pulp & Paper Industry
Controls pneumatic valves, paper-cutter actuators, and flow-directing fork relays in pneumatic conveying pipes across pulping, paper machine dewatering, and coating sections.
Chemical Industry
In fine chemical plants, due to its dual-isolated-group design, it can separately control intermediate relays in hazardous area isolation switchgear and safe areas, implementing production interlock actions.
When operating the DO818 3BSE069053R1 digital output module, strictly ensure that the external process power supply is maintained within the standard 24V DC range to prevent severe voltage fluctuations from disrupting outputs. Because the maximum rated output current per channel is limited to 0.5A, you must install an external flyback diode or an intermediate relay when connecting high-power inductive loads like large solenoid valves or contactors to isolate reverse induced electromotive force. Furthermore, during hot-swapping operations, always verify that the mechanical keying pins of the new module match the existing terminal base coding perfectly to prevent physical damage to the base or short circuits within the internal electronic components caused by forced insertion.
It is an industrial-grade digital output module manufactured by ABB, belonging to the System 800xA and S800 I/O system family, used to transmit switching signals to field industrial equipment.
How to define the core function of the DO818 3BSE069053R1 within a control system?
Acting as a bridge between the process controller and field actuators, it converts internal low-voltage logic signals from the PLC or DCS system into 24V DC switching signals capable of driving external devices.
How many output channels does the DO818 3BSE069053R1 module provide?
This module provides 32 digital output channels, utilizing a highly compact single-point or grouped isolation architecture suitable for high-density signal control.
Which industries are most suitable for configuring the DO818 3BSE069053R1 module?
It is widely used in large-scale Distributed Control Systems (DCS) requiring highly reliable, continuous control, such as oil and gas, large-scale chemical processing, power plants, metallurgy, pulp and paper, and water treatment.
How to securely mount the DO818 3BSE069053R1 inside an electrical cabinet?
It must be plugged into its compatible S800 Terminal Base, which then snaps directly onto a standard 35mm DIN rail, supporting either horizontal or vertical mounting configurations.
