Product Overview
The DI803 (Part Number: 3BSE022362R1) is a high-density digital input module designed for the ABB S800 I/O system, offering seamless integration with AC 800M controllers and Symphony Plus control architectures. This module provides 16 isolated input channels specifically rated for 48 VDC operation, making it ideal for utility-scale power systems and industrial environments that utilize 48V battery banks or long-distance signal loops. By collecting discrete data from field devices such as limit switches, relay contacts, and pushbuttons, the DI803 (3BSE022362R1) ensures precise process monitoring and reliable signal acquisition. Its robust galvanic isolation effectively suppresses field-side electrical noise, maintaining the high levels of expertise and trustworthiness required for critical automation infrastructure.
