ABB DP840 8-Channel Pulse Counter / Frequency Measurement Module, Part Number: 3BSE028926R1 (S800 Distributed I/O Series, Single/Redundancy Supported) Core Function Description This 8-channel high-speed pulse input module belongs to ABB S800 I/O distributed I/O ecosystem for System 800xA DCS and AC 800M controllers. It captures incremental encoder pulses, flow meter pulse signals, rotational speed/frequency signals, and digital switch inputs. Each channel independently supports pulse counting, frequency calculation, and digital input status monitoring with configurable software filters. It supports NAMUR, 12 VDC, and 24 VDC sensor signals, delivers group galvanic isolation to suppress industrial electrical noise, supports hot-swap replacement, and redundant rack deployment for fault-tolera
