The ABB DO930 (Order Code: 3BDS014114) is a specialized digital relay output module engineered for the S900 I/O system. Designed to provide reliable switching in demanding industrial environments, this module features six independent output channels, each capable of handling voltages up to 250V AC/DC with a maximum load current of 2A per channel.

Features

  • Six independent relay output channels with individual isolation.
  • Support for power and communication redundancy to ensure high system availability.
  • Hot-swappable design allows for module replacement without shutting down the entire system.
  • Supports hot configuration in run, enabling parameter adjustments during active operation.
  • Optimized for the S900 I/O architecture.

Applications

The DO930 module is primarily utilized in process automation and control systems where reliable relay-based switching is required for field devices, alarms, or interlocks. It is a standard component for S900 I/O remote I/O stations in oil, gas, and power generation facilities.
