The ABB DO630, identified by order code 3BHT300007R1, is a high-performance 16-channel digital output relay module designed for integration within the Advant OCS control environment. This module provides reliable signal switching for industrial automation applications, offering 16 independent output channels capable of handling 250VAC. Engineered for robustness, it ensures stable operation in demanding industrial environments.

Features

  • 16 independent relay output channels for flexible control logic.
  • High-voltage switching capability up to 250VAC.
  • Fast response time of less than 1ms for critical process timing.
  • Galvanic isolation between channels and the system bus (500VAC) to protect sensitive control circuitry.
  • Integrated overload and short-circuit protection features.
  • Compact, modular design suitable for standard DIN rail or cabinet mounting.

Applications

The DO630 module is primarily utilized in Advant OCS systems for driving actuators, contactors, solenoid valves, and other field-level devices that require relay-based digital switching. Its design makes it suitable for power plants, chemical processing facilities, and large-scale manufacturing infrastructure where high-density I/O and reliable isolation are required.
