Overview

The ABB DO821 (SKU: 3BSE013250R1) is an 8-channel digital output relay module from ABB Process Automation. This module provides 8 individually galvanically isolated channels, each capable of switching 24-230V AC/DC at a maximum of 3A. The relays operate in a normally closed (NC) configuration. It is designed for use with compatible Module Termination Units (MTUs) such as TU811, TU813, TU831, TU836, TU837, or TU851. Key specifications include a power rating of 42W DC and a power factor (cos phi) greater than 0.4 for AC operation. The rated isolation is 250V. The compact dimensions are 45mm width, 102mm depth (111mm with connector), and 119mm height, with a weight of 0.23kg, making it suitable for space-constrained industrial control panels.
