ABB DO620 Digital Output Module

The ABB DO620 (3BHT300009R1) is a 32-channel digital output module designed for the ABB S600 I/O system and Advant OCS distributed control platform. It provides reliable discrete signal switching for industrial automation and process control applications.

Output Configuration and Electrical Ratings

The module features 32 transistor-based digital output channels capable of handling a maximum output voltage of 60 V DC and a maximum output current of 0.5 A per channel. These outputs interface directly with external DC-operated field devices such as relays, solenoid valves, and indicator lamps.

Isolation and Protection Architecture

Outputs are optically isolated and divided into four independent groups of eight channels each, which enhances electrical safety and prevents fault propagation across the system. Furthermore, the outputs incorporate integrated short-circuit protection to safeguard internal circuitry during operational faults.

System Compatibility

The DO620 integrates with the ABB S600 I/O rack architecture and is compatible with Advant Controller 110 and 160 installations within the Advant OCS environment.
