RTD Module Overview
ABB AI830A accepts Pt100, Cu10, Ni100, Ni120 and compatible resistive sensors. Each channel is configured individually, with module linearization and Celsius or Fahrenheit conversion. ABB requires connected RTDs to remain isolated from ground; supervision covers sensor faults, the reference channel and internal power.

System Fit & Termination Units
S800 and Freelance use
ABB lists AI830A in the S800 remote I/O assortment for Freelance, with eight channels for Pt100, Ni100, Ni120, Cu10 and 0–400 Ω resistance measurement.
The reviewed ABB sources do not identify a direct replacement for AI830A. Sensor type, three-wire field wiring, grounding, range, keying and controller hardware definition must all be checked before any substitution.
RTD Fault Patterns
Process temperature measurement
Use Pt100, Ni100, Ni120 or Cu10 elements for machinery, utilities and process temperatures within the engineered sensor range.
Resistance monitoring
Acquire compatible resistive sensors or potentiometer signals through three-wire connections where the field device remains isolated from ground.
Open or shorted sensor loop
Use the channel diagnostic to identify a wiring break or short, then verify field continuity and terminal condition before module replacement.
Unstable or biased temperature
Check sensor type, three-wire lead resistance, equal lead routing, ground isolation and the configured 50/60 Hz MainsFreq setting.
RTD Commissioning Notes
01Confirm the element
Identify Pt100, Cu10, Ni100, Ni120 or the approved resistive sensor.
02Check three wires
Verify field continuity, equal lead routing and the ABB terminal arrangement.
03Prove isolation
Confirm the RTD is isolated from ground before energizing the channel.
04Set and compare
Configure sensor type and 50/60 Hz filter, then compare with a trusted temperature reference.
AI830A is not a thermocouple module. Do not transfer thermocouple wiring, cold-junction assumptions or calibration practice to this RTD input.

AI830A RTD FAQ
Which sensor types can AI830A accept?
ABB lists Pt100, Cu10, Ni100, Ni120 and resistive sensors or potentiometers.
Does AI830A require three-wire RTDs?
Yes. ABB specifies three-wire connections for the supported RTD and resistance inputs.
Can AI830A RTDs be grounded?
No. ABB states that all RTDs connected to the module must be isolated from ground.
How is the mains-frequency filter set on AI830A?
The MainsFreq parameter selects the filter cycle and provides a notch at the specified 50 Hz or 60 Hz frequency.
What diagnostics are available on AI830A?
The module supervises open circuits, short circuits, the reference channel and internal power. It provides module, warning and per-channel error indications.
What should an RFQ for AI830A include?
Send the full part number, quantity, destination, required date and machine or system model. Include the RTD type, installed MTU and controller family if available.
