ABB DOS810 3BSE078768R1 Digital Output Module

Select I/O is an Ethernet-networked, single-channel granular I/O system designed for the ABB Ability™ System 800xA automation platform. It helps decouple project tasks, reduces the impact of late changes, and supports standardization of I/O cabinetry, ensuring automation projects are delivered on time and within budget. Each Signal Conditioning Module (SCM) provides signal conditioning and powering for one connected field device.

The DOS810 is a Digital Output Signal Conditioning Module (24 V / 0.6 A) designed for 2-wire field devices.

Key Features

• Digital Output: Supports 2-wire field devices

• Current Sourcing: 24 V / 0.6 A

• Hazardous Area Use: Can be used in hazardous areas

• Field Power: Sourced from power injection

• Short-Circuit Protection: Electronically current-limited to 0.6 A

• Inductive Load Suppression: Built-in free-wheeling diode

• Galvanic Isolation: Ensures safe operation

• Wrong Wiring Protection: Prevents damage from incorrect connections

Diagnostics and Supervision

• Loop supervision (open circuit and short circuit)

• Hardware error supervision

• Communication supervision

• Internal power supervision

• Power injection supervision

• Output Set to Predetermined value (OSP)

Operational Benefits

• Single-channel granularity: Each SCM handles one I/O channel

• Supports hot swap

• Mechanical locking slider to turn off field device power/output before removal

• Field disconnect function for galvanic separation during commissioning and maintenance

• Electronic current limitation on all SCMs

• Mechanical keying to prevent insertion of incorrect module types

• Powered via 24 V DC through Modulebus

• Configurable through parameters

• LED indicators show operational status of the module
