Description

The AI893 is an 8-channel analog input module designed for use in hazardous areas, featuring intrinsic safety protection on each channel. It supports both 2 and 3-wire RTD sensors and thermocouples (TC). In TC mode, Channel 8 can be configured as a Cold Junction (CJ) channel using a 3-wire Pt100 sensor to measure ambient temperature, serving as the reference for channels 1-7. Alternatively, Channel 8 can function as a regular input channel when CJ measurement is not required. The module enables three-wire connections to process devices without additional terminals and is compatible with TU890 (Ex applications) and TU891 (non-Ex applications).

Features

  • 8 Differential Channels: For 2 or 3-wire RTD and thermocouple inputs
  • Intrinsic Safety: Protection on each channel for hazardous area applications
  • 15 Bit + Sign Resolution: Ensures high-precision measurements
  • Cold Junction Measurement: Channel 8 can serve as a CJ-channel using a 3-wire Pt100 sensor
  • Fixed Junction Temperature: Set by user as a parameter
  • Compact MTU Compatibility: TU890 (Ex applications) and TU891 (non-Ex applications)
  • Diagnostics: Front LEDs for fault, run, and warning status; supervision of open circuit and short circuit for RTD
