The ABB DO810 (3BSE008510R1) is a 16-channel digital output module designed for the S800 I/O system. This module provides reliable, high-side switching for 24 V d.c. applications, making it suitable for driving field devices such as relays, contactors, and indicator lamps within industrial control environments. The module features two isolated groups of eight channels, each equipped with process voltage supervision to ensure system integrity.

The DO810 acts as a digital interface between the control system (e.g., 800xA or Freelance) and field equipment, providing 16 channels of 24 V d.c. outputs for device control.
The module utilizes the OSP (Output Set to Predetermined) function, which allows outputs to transition to a predefined safe state if a communication fault or watchdog timeout occurs.
Each channel is protected against short circuits, over-temperature, and over-voltage conditions. Additionally, the module provides inductive load suppression to protect the internal high-side drivers.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
