Product Overview
The ABB DOS810 (3BSE078768R1) is a Digital Output Signal Conditioning Module (SCM) designed for the ABB Ability™ System 800xA automation platform. It forms part of the Select I/O system, which provides single-channel granularity for flexible and efficient I/O configuration in industrial automation applications.
This module is specifically engineered for controlling 2-wire field devices with a 24V DC/0.6A current sourcing output. Its compact design, robust features, and advanced diagnostics make it suitable for various industrial environments, including hazardous areas.
Key Features
- Single-channel granularity: Each SCM handles one I/O channel, enabling precise control and easy maintenance.
- High reliability: Built-in diagnostics for loop supervision (open/short circuit), hardware errors, and power supply monitoring.
- Safety features: Short-circuit proof with electronic current limitation (0.6A), galvanic isolation, and protection against wrong wiring.
- Hot-swappable: Supports replacement without system shutdown, minimizing downtime.
- Field disconnect function: Allows galvanic separation for safe commissioning and maintenance.
- Mechanical keying: Prevents incorrect module insertion after commissioning.
- Inductive load suppression: Includes a free-wheeling diode for protecting connected devices.
- Wide operating temperature range: -40°C to +70°C, suitable for harsh environments.
