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.

Low inertia loads - pumping or conveyors

XLR-8 provides precise control over soft stopping and is ideal for applications requiring a smoother soft stop. XLR-8 is ideal for low inertia loads such as conveyors. In pumping applications, the EMX3 can eliminate or substantially reduce the effects of water hammer - such as damage to pipes and check valves.

High inertia loads - Circular saws, ball mills

For high inertia loads, XLR-8 lets you take precise control over the motor's stopping time. Shorter stopping times help improve your production efficiency by reducing downtime between operating cycles.

Other applications that benefit from the EMX3 include:

Pumping (e.g. high head applications)
Compressors (for optimising blade control)
Bandsaws (easy blade alignment)
Irrigators (built-in timer)
