IFM Electronic AL2284

IO-Link module

AL2284 IFM module is a specialized solution for integrating temperature sensors into control systems via the IO-Link interface. Unlike standard I/O modules, this device is designed for direct connection of resistance thermometers, converting their analog signal into precise digital data directly in the field.

This four-channel module allows connection of platinum resistance thermometers (Pt100 or Pt1000) using a 2-wire, 3-wire, or 4-wire configuration. The key advantage of the AL2284 is its decentralized installation: the module is installed close to the measurement points, eliminating the need for long and expensive compensation cables and protecting the useful signal from electromagnetic interference typical of industrial environments.
