Extra functions

Temperature compensation

A TC sensor module for internal temperature compensation is provided with the 4 AI TC module, and is fitted on the corresponding terminals of the associated terminal module.

External temperature compensation is possible via a Pt100 on a 4‑AI‑RTD module.

Дизайн


  • The analog electronics modules are installed on terminal modules which must be additionally ordered.
  • The analog electronics modules are plugged as planned onto terminal modules using screw-type systems (TM‑EM/EM60S) or spring-loaded systems (TM‑EM/EM60C).
  • Using a spare module plugged onto a terminal module TM‑EM/EM60S or TM‑EM/EM60C, you can reserve a slot for an analog electronics module or close a gap resulting from how the modules were placed. The spare module can be simply replaced by the envisaged electronics module at a later point in time.
  • The mechanical coding of the terminal module which is carried out when an electronics module is plugged on for the first time prevents the connection of incorrect replacement modules.
  • Hot swapping of individual modules is possible under hazardous conditions.
  • The process signals are connected to the terminals of the terminal modules assigned according to the plan, using either conventional screw-type or spring-loaded systems (conductor cross-sections 0.14 mm² to max. 2.5 mm²) depending on the type of module.
