Communication modules

The EMX3 supports network communication using Profibus, Profinet, DeviceNet, Ethernet/IP, Modbus RTU or Modbus TCP protocols, via easy-to-install communication interfaces.

Finger guards

Enhance personnel safety by preventing accidental contact with live terminals. The finger guard kit fits EMX3-0220B to EMX3-1000B and provides IP20 protection when used with cables 22 mm or greater.

Input/output card

Add extra inputs and outputs for advanced integration:

  • 2 x inputs
  • 3 x relay outputs
  • 1 x analog input
  • 1 x analog output

RTD and ground fault

  • 6 x PT100 RTD inputs
  • 1 x ground fault input

To use ground fault protection a 1000:1,  5 VA current transformer is also required.

PC Software

Using AuCom's custom designed WinMaster software you can control, monitor and program your EMX3 from your desktop computer.
