ABB AI830A – 8-Channel RTD Analog Input Module | S800 I/O for AC 800M DCS
Engineering Background
The ABB AI830A is a high-precision 8-channel RTD (Resistance Temperature Detector) analog input module designed for ABB’s S800 I/O platform, fully compatible with the AC 800M Process Automation Controller. As part of ABB’s proven Freelance and System 800xA DCS architecture, the AI830A delivers reliable temperature measurement in demanding industrial environments where accuracy and signal integrity are non-negotiable.
Product Positioning
Engineered for process industries including oil & gas, chemical, power generation, and pulp & paper, the AI830A serves as the primary field interface for RTD-based temperature loops. Its galvanically isolated channels and high common-mode rejection make it the preferred choice for procurement engineers specifying S800 I/O expansions or system upgrades on existing AC 800M installations.

Proven Application Environments
- Oil & Gas: Wellhead and pipeline temperature monitoring integrated into AC 800M-based SCADA/DCS systems.
- Chemical Processing: Reactor and heat-exchanger temperature loops requiring high accuracy and channel isolation.
- Power Generation: Turbine bearing and winding temperature measurement in combined-cycle and thermal plants.
- Pulp & Paper: Digester and dryer temperature control within System 800xA process networks.
- Water & Wastewater: Multi-point temperature profiling in treatment plant automation.
- Pharmaceutical: GMP-compliant temperature acquisition for validated batch processes.
Engineering Advantages
- Multi-wire RTD support: Configurable per channel for 2-, 3-, or 4-wire connections, eliminating lead-resistance errors in 4-wire mode.
- Galvanic isolation: Prevents ground loops and protects the controller bus from field-side transients.
- Hot-swap capability: S800 I/O modules support online replacement without shutting down the controller or adjacent channels.
- Integrated diagnostics: Open-circuit, short-circuit, and out-of-range detection reported directly to the AC 800M controller via ModuleBus.
- Compact footprint: Single-slot form factor maximizes cabinet density in S800 I/O clusters.
- Wide sensor compatibility: Supports all common industrial RTD types without external signal conditioners.
System Architecture & Signal Flow
The AI830A mounts directly onto an S800 I/O ModuleBase (TB820V2 or equivalent), which connects to the AC 800M controller via a redundant or simplex ModuleBus optical or electrical link. Field RTD sensors wire to the module’s terminal block on the ModuleBase. The module performs A/D conversion and linearization onboard, transmitting engineering-unit values to the AC 800M CPU over the high-speed I/O bus. Configuration and channel parameterization are performed in ABB Control Builder M or System 800xA Engineering Studio without requiring hardware jumpers.
Sourcing & Quality Verification

Technical FAQ
- Q: Is the AI830A compatible with AC 800M firmware 6.x and later?
- A: Yes. The AI830A is supported across all AC 800M firmware generations. Confirm the module revision (Rev. C or later recommended) for full feature support in newer firmware.
- Q: Can I mix AI830A with other S800 I/O modules on the same ModuleBase?
- A: Yes. S800 I/O ModuleBases support mixed module types. Ensure the total bus current draw does not exceed the ModuleBase power budget.
- Q: What is the difference between AI830A and AI830?
- A: The AI830A is the revised version with improved EMC performance and extended operating temperature range. It is backward-compatible with all AI830 installations.
- Q: Does the module support HART pass-through?
- A: No. The AI830A is a dedicated RTD input module and does not support HART communication. For HART-enabled analog inputs, refer to the ABB AI835A.
- Q: Can channels be individually configured for different RTD types?
- A: Yes. Each of the 8 channels is independently configurable for sensor type, wire mode, and engineering unit range via Control Builder M software.
