ABB DO821 3BSE013250R1 Digital Output Module
Manufacturer: ABB
Product Number: DO821 (3BSE013250R1)
Category: 8-Channel Digital Output Module (S800 I/O System)
Number of Channels: 8
Output Type: Relay, Normally Closed (NC)
Maximum Voltage: 250 V AC
Maximum Current: 0.5 A per channel (continuous)
Operating Temperature: -20°C to +60°C
Power Supply: 24 V DC
Product Description
The ABB DO821 3BSE013250R1 Digital Output Module is an 8-channel 230 V a.c./d.c. relay Normally Closed (NC) output module designed for the S800 I/O system. It supports a maximum voltage of 250 V a.c. and a maximum continuous output current of 3 A, making it suitable for industrial environments that demand high reliability and safety. Each output channel is independently isolated, featuring optical isolation barriers, output state indication LEDs, relay drivers, relays, and EMC protection components to ensure stable and secure outputs. The module also integrates relay power supply voltage supervision; in case of power failure, it triggers an error signal and activates a warning LED. Error signals can be read through the ModuleBus, providing continuous monitoring and fault diagnosis.
Key Features
- 8 Channels for 230 V a.c./d.c. relay NC outputs
- Independently Isolated Channels: Provides electrical isolation for each channel.
- Output Status Indicators: Each channel is equipped with an LED indicator showing real-time output status.
- Error Detection Mechanism: The module uses OSP to set outputs to a predetermined state upon error detection.
- Relay Power Supply Supervision: Monitors 24V power supply; when lost, it generates an error signal and activates the warning LED.
- Module Monitoring & Diagnostics: Real-time monitoring of the module and channels, with error signals readable via the ModuleBus.
