ABB DO802 Digital Output Relay 8 Ch

Description

The ABB DO802 Digital Output Relay 8 Ch is a digital output module designed for integration with the S800 I/O system. Its core function is to receive digital signals from a PLC and drive external relays to control connected external devices. Key features include a multi-channel design, with standard configurations offering 8 or 16 relay output channels to enable simultaneous control of multiple devices. Each output channel incorporates isolation protection, which blocks external interference and significantly boosts overall system reliability. The module uses a modular design for simplified installation and maintenance, and its industrial-grade construction ensures stable operation in harsh industrial environments. It also supports flexible software configuration for different relay types and contact forms, including normally open, normally closed, and changeover contacts.

Technical specifications include a millisecond-level response time, an operating temperature range of -20 degrees Celsius to 60 degrees Celsius, and a protection rating of IP20 or higher. For 8-channel models, output voltage ranges from 24V to 230V AC or 110V DC, with a maximum current of 2A per channel and a load capacity of less than 60W; each channel has an isolation voltage rating of 250V. This module is suitable for use in industrial automation scenarios such as process control, factory equipment management, and power system automation.
