ABB AI893 Analog Input Module (3BSC690141R1)
Product Description
The ABB AI893 (3BSC690141R1) is an advanced analog input module specifically engineered for safe and accurate temperature measurement in industrial automation systems. It includes eight channels, each equipped with intrinsic safety protection, enabling direct connection to field devices in hazardous areas without additional safety barriers. Moreover, it supports both thermocouples (TC) and RTD sensors, providing flexible deployment across process control applications.
The module can be configured for either two‑ or three‑wire RTD connections or thermocouple sensors, with channel 8 serving as a cold-junction measurement for channels 1–7 in TC mode. Therefore, it ensures precise temperature compensation even in challenging installations. In addition, the module allows the cold-junction temperature to be measured locally on the MTU terminals or remotely, with the option for a user-defined fixed junction temperature.
Compatibility with TU890 and TU891 compact MTUs enables three-wire connections to process devices without extra terminals. For instance, TU890 supports hazardous area (Ex) installations, while TU891 is suitable for non-Ex environments, simplifying integration into existing S800 I/O systems.
