ABB DP840 is an S800 I/O pulse counter module identified by manufacturer article number 3BSE028926R1. ABB specifies eight independent channels that can measure pulse count or frequency up to 20 kHz, while the inputs may also be read as digital signals. Each channel includes a configurable input filter, and the module performs cyclic self-diagnostics with advanced diagnostic support. DP840 accepts NAMUR, 12 V and 24 V transducer signal levels and supports single or redundant applications. Before replacement, verify the model, article number, termination unit, input level, filter, measurement mode, redundancy arrangement and controller configuration.
Condition, availability and warranty are Stockoems commercial information, not ABB manufacturer commitments.
Receive NAMUR, 12 V or 24 V transducer signals on configured channels.
Apply the independently configured channel input filter.
Count pulses or calculate frequency within the documented range.
Transfer measured values and diagnostic information through S800 I/O.
Verify the complete DP840 designation and 3BSE028926R1 article number, installed module termination unit, NAMUR or voltage input level, channel filter, pulse or frequency mode, redundancy arrangement and controller configuration before replacement. ABB lists TU810V1, TU812V1, TU814V1, TU830V1 and TU833 for use with DP840; the installed wiring and station design must determine the exact selection.

The workflow combines inspection planning, identity and label verification, technical compatibility review, protective handling, shipment coordination, tracking support, customs-file preparation and documented after-sales communication. Availability and delivery timing are provided only through written commercial communication; no unverified stock quantity or delivery promise is presented.
Choose a supplier that preserves the complete model, states condition clearly, requests label evidence and separates commercial terms from manufacturer specifications.
Request written model identity, article number, quantity, condition, warranty scope, packaging, shipping basis, customs documents and return rules.
Provide installed labels, termination-unit type, channel wiring, redundancy design, controller configuration, software revision and project backup.
Shortened model strings, copied data from similar modules, vague condition wording, unverifiable quantities, missing label evidence and absent return terms require caution.
