ABB DO840 3BSE020838R1 Digital Output Module

製品紹介

The ABB DO840 3BSE020838R1 is a high-performance 16-channel digital output module designed for use in the ABB S800 I/O system. Engineered for demanding industrial environments, the DO840 provides reliable signal transmission from the control system to field devices such as relays, contactors, solenoids, and indicator lamps.

This module delivers 24 V DC output signals and ensures electrical isolation for each output channel. With built-in protection features including short-circuit protection and thermal shutdown, the DO840 is ideal for critical applications where safety and stability are paramount. Each channel is individually monitored and equipped with an LED indicator for real-time diagnostics, simplifying troubleshooting and maintenance.

The compact design (45 x 102 x 119 mm) allows efficient panel space usage, and the lightweight build (0.15 kg) facilitates easy installation. The DO840 is compatible with AC 800M controllers and fully integrates into ABB’s 800xA control systems, enabling seamless automation architecture deployment.
