Description

The AI835A is an 8-channel differential input module designed for precise thermocouple and millivolt (mV) measurements. It supports a wide range of thermocouple types (B, C, D, E, J, K, L, N, R, S, T, U) and linear mV inputs (-30 mV to +75 mV). Channel 8 can be configured as a Cold Junction (CJ) channel using a 4-wire Pt100 RTD for ambient temperature measurement, serving as the reference for channels 1-7. Alternatively, it functions as a regular input channel when CJ measurement is not required.

Features

  • 8 Differential Channels: For thermocouple and mV measurements
  • Channel 8 as CJ-Channel: Configurable for cold junction temperature measurement
  • Thermocouple Types: B, C, D, E, J, K, L, N, R, S, T, U
  • Linear mV Range: -30 mV to +75 mV
  • 15-Bit Resolution: Ensures high-precision measurements
  • Wire-Break Detection: Monitors for open-circuit conditions
  • Customizable CJ Temperature: Set by user or application
  • Diagnostics: Front LEDs for fault, run, and warning status; supervision of open-circuit, reference channels, and power supply
