TU810, TU812, TU814, TU818, TU830, TU833, TU835, TU838 and TU850. The hardware-selector keying code is AE.
Signal Module Overview
ABB AI810 provides eight single-ended inputs in one group isolated from ground. Each channel can be set for a supported current or voltage range. PTC protection is fitted to the current shunts, and ABB states that the current and voltage inputs withstand at least 30 VDC without damage.

S800 system integration
ABB lists AI810 in S800 I/O and in the S800 remote I/O assortment for Freelance, which communicates with Freelance controllers via PROFIBUS.
ABB does not identify a direct replacement in the reviewed sources. A visually similar eight-channel module may have different voltage ranges, HART handling, diagnostics, MTU keying or transmitter-power arrangements.
Current-Loop Fault Patterns
Conventional 4–20 mA loops
Connect standard current transmitters where HART pass-through is not part of the required maintenance workflow.
0–10 V process signals
Acquire unipolar voltage signals from drives, converters or analyzers within the specified range and isolation arrangement.
Channel reading fixed high or low
Check channel range selection, field polarity, common return, transmitter power and wiring before changing the module.
Several channels fail together
Because the eight channels form one group, inspect the group return, MTU, ModuleBus connection and internal power-supply diagnostic state.
Loop Commissioning Notes
01Identify the signal
Confirm 0/4–20 mA or 0/2–10 V and the intended single-ended wiring.
02Match the MTU
Use an ABB-listed MTU and verify the AE mechanical keying arrangement.
03Configure the channel
Select the current or voltage range for each channel in the controller hardware configuration.
04Prove the loop
Compare the field signal, scaled value and F/R/W indications before return to service.
The selector marks HART as “No.” ABB separately states that the input withstands HART communication; this is not a claim of HART pass-through or asset-management support.

AI810 Signal & Procurement FAQ
Can AI810 use current and voltage inputs on different channels?
Yes. ABB states that each channel can be configured as a supported current or voltage input.
Does AI810 provide HART pass-through?
No. The hardware selector marks HART as “No.” The statement that the input withstands HART communication should not be read as pass-through support.
Which MTUs are listed for AI810?
ABB lists TU810, TU812, TU814, TU818, TU830, TU833, TU835, TU838 and TU850. The keying code is AE.
What diagnostics are available on AI810?
The module has F, R and W front LEDs, internal power-supply supervision and module, warning and channel status indications.
What should be checked when an AI810 reading is incorrect?
Verify the configured range, field polarity, common return, transmitter supply, loop signal, MTU seating and ModuleBus status before replacing the module.
What should an RFQ for AI810 include?
Send the full part number, quantity, destination, required date and machine or system model. The installed MTU and input range are useful for a compatibility review.
