ABB DO814 3BUR001455R1 Current Sinking DO

Product Overview

The ABB DO814 is a high-density, 24V DC digital output module designed for the S800 I/O system. Featuring 16 current-sinking outputs, this module is engineered for driving loads like solenoids, relays, and pilot lights in industrial automation environments. With integrated short-circuit protection and group-wise isolation, the DO814 provides a balance of high-channel density and robust electrical safety for the AC 800M controller platform.

Core Performance Features

• Current Sinking Design: Specifically built for sinking configurations, allowing the module to act as the ground path for your field loads.

• Dual-Group Isolation: The 16 channels are divided into two isolated groups of 8, preventing a fault in one power circuit from affecting the entire module.

• Short-Circuit Proof: Each output is capable of handling 0.5A and includes built-in protection against short circuits, significantly reducing the risk of hardware damage during field wiring faults.

• Extensive MTU Compatibility: Highly flexible installation options; compatible with a wide range of Module Termination Units (MTUs) including the TU810, TU830, and TU833.

• Compact 45mm Housing: Optimized for high-density cabinet layouts, delivering 16 outputs in a slim-line form factor.
