A field terminal is a replaceable unit used to terminate field wiring and link it directly to the I/O module. By separating the terminal block from the module, a damaged terminal block doesn’t mean replacement of the module. Any required field device power can be provided via the module to the field terminals, so no further patching is required. The modules have recommended field terminal types, not only to maximise usability but also to maintain safety, by preventing the wrong type of module from being connected to the field devices. Other key benefits include:

  — Fuses or loop-disconnects for protection
  — Mechanical keying for correct module identification
  — Blue field terminals to identify IS field wiring
  — Tagging strip for easy identification of field device wiring
  — Built-in cold junctions for field thermocouples
