AI895
ABB
Overview
The AI895 is an Analog Input from ABB. It provides 8 channels and is built for signal interfacing within the ABB product portfolio systems.
Application & Technical Notes
As an analog input, the AI895 is intended for deployment in panel-based control cabinets and machine enclosures where the ABB product portfolio equipment is installed. It converts field signals (sensors, switches, transmitters) into the digital or analogue values the controller processes, forming the acquisition layer of the automation scheme.
Key published characteristics include 8 channels. These values should be confirmed against the current manufacturer datasheet before final selection, as options and suffixes vary by configuration.
Maintenance & Diagnostics
Avoid condensation — the rated humidity is 5 to 95 %, non-condensing; store and operate the module in a dry, pollution-degree-appropriate enclosure. Verify field wiring, shielding and grounding at installation; check terminal torque and confirm signal types match the configured range. Periodically inspect for loose terminations, induced noise and channel-level diagnostics reported by the controller. Always de-energise the circuit and follow lock-out/tag-out before handling; refer to the official instruction bulletin for service procedures.
Sourcing & Procurement
When sourcing the AI895, distinguish three supply tiers: (1) genuine ABB stock from an authorised distributor; (2) compatible equivalents or surplus/NOS (new-old-stock) from third parties; (3) alternative parts offering equivalent function. Genuine supply carries the full warranty and traceability; compatible or alternative items may be cheaper but should be validated for form, fit, firmware and certification before use in a live system. PLCXpert publishes this page as an independent reference and does not sell the part — verify every claim with the manufacturer or your distributor.
Confirm the module matches your ABB product portfolio rack, the required channel count, signal type and voltage, and the firmware/configuration of the controller. Lead times and pricing vary by region and lifecycle status; obtain a current quote from an authorised channel rather than relying on stale listings.

Is the AI895 compatible with my controller?
It belongs to ABB's automation product portfolio. Confirm the specific rack, firmware revision, slot rules and configuration with the controller documentation before purchase, as compatibility depends on the exact system build.
What should I check before buying the AI895?
Verify the genuine part number and suffix, confirm it matches your platform and ratings, check the current lifecycle/availability status, and buy from an authorised distributor. PLCXpert provides this reference only and does not sell the component.
Specifications
The AI895 Analog Input Module can directly interface 2-wire transmitters and with a particular connection it can also interface 4-wire transmitters without losing the HART capability. The AI895 Analog Input Module has 8 channels. The module includes Intrinsic Safety protection components on each channel for connection to process equipment in hazardous areas without the need for additional external devices. Each channel can power and monitor a two-wire process transmitter and HART communication. The input voltage drop of the current input is typically 3 V, PTC included. The transmitter supply for each channel is able to provide at least 15 V at a 20 mA loop current to power Ex certified process transmitters and is limited to 23 mA in overload conditions.
