Eight unipolar channels for current, voltage and HART process measurement.
ABB AI845 is an S800 I/O analog input module for single or redundant process measurement. It provides eight single-ended unipolar channels for 0...20 mA, 4...20 mA, 0...5 V or 1...5 V d.c. signals. When TU844 or TU845 is used, channels can be configured individually for voltage or current; with other supported MTUs, all channels use the same signal type. ABB specifies 12-bit resolution, HART pass-through communication, supervised current-limited transmitter supply and advanced on-board diagnostics. Replacement planning should verify the exact AI845 designation, MTU, signal mode, redundancy arrangement, field wiring and controller engineering.
Condition, availability and warranty are Stockoems commercial terms.
Eight single-ended unipolar channels accept current or voltage process signals.
The module supports single or redundant S800 I/O applications.
HART pass-through and supervised transmitter supply support intelligent field devices.
Verify the exact AI845 designation, selected current or voltage mode, supported MTU, HART requirement, transmitter supply, redundancy configuration, field wiring, ModuleBus arrangement and controller engineering before replacement. With TU844 or TU845, channels may be configured individually; other MTUs apply one signal type across all channels. AI815 is not a direct substitute.

A documented route for identity checks, technical review, condition evidence, protective handling and international delivery coordination.
Model and suffix verification, condition confirmation, technical compatibility review, and product and label photo confirmation are completed against the purchasing request.
Protective packaging is selected for industrial electronics, with attention to connectors, terminals, housing edges and moisture control.
Worldwide shipping, shipment tracking and customs documentation are coordinated after destination and transport requirements are reviewed.
Our service advantage is a traceable workflow linking product identity, photo evidence, packaging preparation, logistics coordination and document readiness. Lead time and quantity are confirmed only after an actual availability review.
Request the complete model and suffix, clear condition terms, current product and label photos, written warranty coverage, and a documented return process.
Confirm legal company details, quotation consistency, traceable communication, packaging scope, shipping documents and payment instructions before placing an order.
Unclear suffixes, reused photos, missing label evidence, unsupported compatibility claims, pressure for immediate payment and refusal to document warranty or returns are common risk signals.
Share the complete part number, quantity, destination country and product label photos for availability, condition, compatibility and shipping review.
