ABB AI835A Analog Input Module for S800 I/O Systems
Product Overview
The ABB AI835A Analog Input Module is designed for the ABB S800 I/O platform, providing 8 differential input channels for thermocouple and millivolt (mV) signal measurement. Each channel can be configured individually to measure -30 mV to +75 mV linear signals or a wide range of thermocouple types, including B, C, D, E, J, K, L, N, R, S, T, and U.
One of the module's key features is Channel 8, which can be configured as a Cold Junction (CJ) compensation channel using a 4-wire Pt100 RTD, or used as a standard measurement channel when CJ compensation is not required. With 15-bit A/D resolution and built-in wire-break detection, the AI835A supports accurate temperature measurement and reliable signal monitoring for industrial process automation applications. It is suitable for new installations, system upgrades, and replacement projects within ABB S800 I/O systems.

Key Features & Benefits
Flexible Temperature Measurement - The AI835A supports multiple thermocouple types and millivolt inputs, allowing a single module to accommodate different temperature measurement requirements across a wide range of industrial processes.
Integrated Cold Junction Compensation - By allowing Channel 8 to function as a dedicated Cold Junction compensation channel, the module helps improve the accuracy of thermocouple measurements without requiring additional external compensation devices.
Reliable Signal Monitoring - With 15-bit resolution and integrated wire-break detection, the AI835A helps maintain stable measurement quality while allowing maintenance personnel to identify open-circuit conditions quickly, supporting reliable process operation.
Engineering Note
When thermocouple measurements are used in process control, proper cold junction compensation is essential for maintaining measurement accuracy. Configuring Channel 8 as the dedicated CJ channel, when required by the application, helps ensure consistent temperature readings while simplifying module configuration.

Frequently Asked Questions
Q1: What signals can the ABB AI835A measure?
The AI835A supports millivolt (-30 mV to +75 mV) inputs and thermocouple types B, C, D, E, J, K, L, N, R, S, T, and U.
Q2: What is the purpose of Channel 8?
Channel 8 can be configured as a Cold Junction (CJ) compensation channel using a 4-wire Pt100 RTD, or it can operate as a standard analog input channel when CJ compensation is not required.
Q3: Does the AI835A provide diagnostic functions?
Yes. The module monitors its inputs for wire-break (open-circuit) conditions, helping users detect field wiring faults more efficiently.
