Official Full Product Name & Function Description Official Full Name: ABB DI801 16-Channel 24V DC Digital Input Module, Article Number 3BSE020508R1 Product Series: S800 Distributed I/O System for ABB System 800xA Industrial IT DCS & AC 800M Controllers Core Function: High-density digital sink input module to collect discrete 24VDC on/off signals from field-side sensors, limit switches, pressure switches, proximity sensors, relay feedback contacts and pulse counters. All 16 channels share single-group optoelectronic isolation to block field EMI interference. Channel 16 supports dedicated group voltage supervision for circuit fault detection. It transmits digital status data to AC 800M controllers via S800 fieldbus, supports software-configurable input debounce filters to eliminate contact b
