Product Overview:

The ABB AI890 3BSC690071R1 is a high-performance analog input module designed for use in hazardous areas with intrinsic safety protection components. The module is equipped with 8 channels that support 0…20 mA or 4…20 mA unipolar, single-ended inputs. These inputs are suitable for connection to both powered and unpowered two-wire process transmitters. With the ability to monitor and power Ex-certified process transmitters, the AI890 module is a robust solution for industrial automation in potentially hazardous environments.

Each channel is isolated from the others and features a built-in power and monitor function, offering protection without the need for external safety devices. The module operates efficiently with a loop current of 20 mA and a voltage drop of around 3 V per channel. The module is powered by a 24 V supply and offers overload protection up to 23 mA.

The AI890 module is compatible with ABB’s TU890 and TU891 Compact MTU. The TU890 variant is designed for Ex applications, while the TU891 is meant for non-Ex scenarios.

Key Features & Benefits:

• 8 channels supporting 0…20 mA or 4…20 mA inputs.
• Each channel features intrinsic safety protection for hazardous area connections.
• Supports externally powered two-wire process transmitters.
• Input voltage drop of approximately 3 V (including PTC).
• Provides at least 15 V at 20 mA loop current to power Ex-certified transmitters.
• 1 group of 8 isolated channels from the ModuleBus and power supply.
• Compact and reliable solution for applications requiring high safety standards.
