TCP/IP interface

The built-in LAN TCP/IP interface is protected against dirt and manipulation.
You can analyse different measurement readings via your web browser and IP address in a LAN or WAN.

  • Remote reading via Modbus TCP  
  • NTP time server
  • Buffered clock with synchronisation
  • DHCP or fixed IP

Modbus TCP
Modbus TCP is similar to Modbus RTU, but TCP/IP packages are used to transfer data. TCP-Port 502 is reserved for Modbus TCP.

Power meter readings

  • Active energy consumption (kWh) and supply (kWh)
  • Reactive energy consumption (kvarh) and supply (kvarh)
  • Active power (kw) 
  • Reactive power (kvar) 
  • Apparent power (kVA)
  • Current (A)
  • Frequency (Hz)
  • Number of voltage failures


Reading and setting parameters is user-friendly by a 38x28 mm graphic LCD display with LED backlight. This provides excellent visibility of numbers and letters.
Display language e.g. english or german can be selected by the keys.

Power meter configuration

Touch-sensitive control buttons are used for configuration. A sealable service button must be pressed for each configuration change.
Network parameters are easy to configure via the website.

S0 pulse output

The 3-phase power meter EMU Professional II 3/100 TCP/IP features a configurable S0 pulse output for active or reactive energy 

  • Pulse rate per kWh / kvarH: 1,10,100, 1000 or 10000
  • Pulse length in milliseconds: 2ms, 10ms, 30ms, 40ms, 120 ms

Power meter configuration ex factory

  • Netwok configuration: DHCP
  • S0 pulse output: 1'000 Impulse/ 40 ms
