Product Features
ABB DO821 3BSE013250R1 features 8 230V AC/DC relay normally closed (NC) output channels, with all 8 channels being isolated.
ABB DO821 3BSE013250R1 includes output status indicators to display the output status.
Equipped with OSP functionality, ABB DO821 can set the output to a predefined state when an error is detected.
ABB DO821 3BSE013250R1 has front-panel LED indicators, including F (Fault), R (Running), W (Warning), O (SP), and status indicators for channels 1-8.
ABB DO821 3BSE013250R1 has a 24/12V relay power converter monitoring function, providing monitoring status indicators for module errors, module warnings, channel errors, and more.
Product Using Principle
ABB DO821 3BSE013250R1 Digital Output Module receives control signals via ModuleBus. Each output channel is electrically isolated from other parts through optical isolation barriers to ensure system safety. The relay driver activates the relay based on the control signals, thereby controlling the on/off status of external devices.
Output status indicator LEDs display the real-time operational status of each channel. When an error is detected, the OSP function sets the output to a predetermined state, and the warning LED illuminates. The error signal can be read via ModuleBus, and users can enable or disable the relay power voltage monitoring function through parameters.
