AI895 3BSC690089R1 | ABB 8-Channel Multifunction Analog Input Module
The ABB AI895 (3BSC690089R1) is an 8-channel multifunction analog input module designed for ABB S800 I/O systems. It acquires current, voltage, RTD and thermocouple signals from field instruments, converts them into digital data, and provides reliable process inputs for PLC, DCS and control systems.
This module supports channel-level configuration, allowing different signal types to be configured within the same module. It is suitable for temperature, pressure, flow and level measurement applications in process automation, power generation, chemical, oil and gas, and water treatment systems.
- 8 analog input channels, configurable per channel
- Supports current, voltage, RTD and thermocouple signals
- Multifunction input capability reduces the need for separate specialized modules
- Open-circuit detection for current, RTD and thermocouple inputs
- LED status indicators for module and channel diagnostics
- SOE-ready diagnostics for event recording applications
- Hot-swappable design with compatible S800 I/O termination units
- Compatible with ABB System 800xA, AC 800M and Freelance systems
- Temperature measurement using RTD and thermocouple sensors
- Pressure, flow and level transmitter input
- DCS and PLC analog input expansion
- System 800xA and AC 800M process control projects
- Freelance DCS I/O configuration
- Retrofit and spare-part replacement for existing S800 I/O stations

We supply ABB S800 I/O modules for global industrial automation projects. Please contact our sales team with your required quantity, destination country, controller type and termination unit model. We can assist with product confirmation, lead time and available documentation.
No. AI810 is typically used for current/voltage inputs, AI835 is designed for thermocouple/mV signals, and AI895 is a multifunction module that can support multiple signal types. Replacement depends on the controller configuration, termination unit and signal requirements.
AI895 is used with compatible S800 I/O termination units. The correct TU/TB model should be confirmed with the official ABB documentation and the existing I/O station design.
Redundancy support depends on the controller, system configuration and termination unit. Please verify with the official ABB product guide before implementation.
We can provide available product information upon request. For official specifications, always refer to the ABB datasheet or authorized documentation.
