Product Description
The DO840 Digital Output Module (3BSE008510R1) is a 16-channel current sourcing module in ABB’s S800 I/O system. It provides robust and flexible output control, designed for industrial environments requiring high reliability, diagnostics, and protection against overloads and short circuits.
Features and Benefits
-
16 Digital Output Channels:
- For 24 V DC current sourcing outputs.
- Divided into two isolated groups of 8 channels with individual process voltage supervision.
-
Comprehensive Protection:
- Short-circuit protection to ground and over 30 V.
- Over-voltage and over-temperature protection.
- Current-limited outputs with fault recovery.
-
Output State Preservation (OSP):
- Automatically sets outputs to a pre-determined state upon error detection.
-
Diagnostics and Monitoring:
- Real-time process voltage supervision per group.
- LED indicators for fault, warning, and output channel statuses.
-
Compatible with Multiple MTUs:
- TU810, TU812, TU814, TU830.
