Description

The AI895 is an 8-channel analog input module designed for interfacing with 2-wire transmitters and, with a specific connection, 4-wire transmitters while maintaining HART communication capabilities. It includes intrinsic safety protection on each channel, enabling direct connection to process equipment in hazardous areas without additional external devices. The module can power and monitor two-wire process transmitters, with a typical input voltage drop of 3 V (PTC included). Each channel provides at least 15 V at 20 mA loop current to power Ex-certified transmitters, limited to 23 mA in overload conditions. Compatible with TU890 (Ex applications) and TU891 (non-Ex applications).

Features

  • 8 Channels: For 4...20 mA, single-ended unipolar inputs
  • HART Communication: Supports HART protocol
  • Intrinsic Safety: Protection on each channel for hazardous areas
  • Power and Monitor: For Ex-certified two-wire transmitters
  • Non-Energy-Storing Inputs: For externally powered sources
  • Compact MTU Compatibility: TU890 (Ex) and TU891 (non-Ex)
  • Diagnostics: Front LEDs for fault, run, warning, and HART communication status; supervision of internal process supply
