ABB DI840 is an S800 I/O digital input module identified by manufacturer article number 3BSE020836R1. ABB specifies sixteen 24 V DC current-sinking channels in one group with a common return, extended diagnostics, time-tagging and a current-limited sensor supply. The module can be used in single or redundant configurations. Its role is to receive discrete field signals while supporting diagnostic and event information within the engineered I/O station. Before replacement, confirm the exact DI840 designation, article number, module termination unit, channel wiring, redundancy arrangement and controller configuration. Stockoems commercial terms remain separate from ABB specifications.
Condition, availability and warranty are Stockoems commercial information, not ABB manufacturer commitments.
Receive 24 V DC current-sinking inputs from configured field contacts or sensors.
Process sixteen channels in one group using the documented common return.
Provide extended diagnostic and time-tagging information to the engineered station.
Transfer validated input states through the S800 I/O communication architecture.
Verify the complete DI840 designation and 3BSE020836R1 article number, installed module termination unit, 24 V DC field wiring, common return, channel allocation, redundancy arrangement, controller configuration and software project before replacement. ABB documentation lists compatible termination-unit families, but the installed wiring and station design must determine the exact selection. Similar S800 digital input modules are not automatically interchangeable.

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.
