Description

The AI890 is an 8-channel analog input module designed for use in hazardous areas. It features intrinsic safety protection on each channel, allowing direct connection to process equipment without additional external devices. The module supports both current inputs (0...20 mA or 4...20 mA) and power supply for Ex-certified two-wire transmitters. All eight channels are isolated from the ModuleBus and power supply in one group, ensuring reliable operation in industrial environments.

Features

8 Channels: For 0...20 mA or 4...20 mA, single-ended unipolar inputs
Intrinsic Safety: Protection on each channel for hazardous area applications
Power Supply: Built-in 15 V at 20 mA loop current for Ex-certified two-wire transmitters, limited to 23 mA in overload
Non-Energy-Storing Inputs: For externally powered sources
Compact MTU Compatibility: TU890 (Ex applications) and TU891 (non-Ex applications)
Diagnostics: Front LEDs for fault, run, and warning status; supervision of internal process supply
