ABB DO820 3BSE008514R1 Digital Output Relay Module
The DO820 is an 8-channel normally open relay output module designed for the S800 I/O system. Each channel supports up to 250 V AC/DC with a maximum continuous current of 3 A. All outputs are individually isolated and include optical isolation barriers, relay drivers, relays, EMC protection components, and status LEDs for output indication. This module is ideal for distributed automation systems requiring reliable relay operation.
Relay supply voltage supervision is derived from the 24 V ModuleBus. If the supply voltage is lost, the module generates an error signal and illuminates the Warning LED. The error status can be read via the ModuleBus, and supervision functionality can be enabled or disabled through parameter settings for seamless system integration.
Key Specifications
8 channels for 230 V AC/DC relay Normal Open (NO) outputs
8 individually isolated channels
Output status indicators for each channel
OSP (Output Safe Position) sets outputs to predetermined state upon error detection
