Programmable via PC or DIP switches, the DAT4631A offers flexibility and ease of use.

Key Features

  • Wide Thermocouple Compatibility: Supports multiple thermocouple types, including J, K, S, R, B, E, T, and N.
  • mV Signal Handling: Accepts millivolt inputs up to 800mV.
  • Linearized Output: Converts and linearizes the input signal for accurate representation.
  • Cold Junction Compensation: Ensures precise temperature readings by compensating for cold junctions.
  • Versatile Output Options: Provides two isolated voltage or current outputs to meet various application requirements.
  • High Accuracy: Delivers precise measurements for critical applications.
  • Isolated: Ensures signal integrity and safety by providing isolation between input, output, and power supply.
  • PC and DIP Switch Programmable: Offers easy configuration through PC software or manual DIP switches.

The DAT4631A is ideal for applications requiring reliable and accurate temperature measurement and signal conversion. Whether for industrial processes, research, or automation, the DAT4631A delivers dependable performance and flexibility.
