PLC for low-voltage network

Created with Sketch.

Powerline modems

with RS232/RS485 interface for 230 / 400 V networks

 

Key feautures

  • Designed for normal 230 V / 50 Hz lines
  • Both sigle and three phase version available
  • Communication rate 10 kbit/s
  • Excellent noise immunity thanks to an advanced error correction – FEC
  • High output power
  • Easy configuration thanks to a simple RSet utility for Windows

Typical application

  • Smart grid (e.g. remote meter readings)
  • Home automation
  • Industrial automation
  • Perfect for transfer of Modbus, IEC 62056-21, DLMS

Reliable communication

The communication channel provided by the modem is characterized by its excellent noise immunity, very long reach without repeaters or protocol flexibility thanks to transparent data transfer. There are also possibilities including routing, addressing, repeating etc.

Single-phase and three-phase solution

There is an MT34R model that is capable of bidirectional communication on all three phases. The more compact MT49R is then designed for single-phase connection. The ideal solution is where the MT34R forms the master (MASTER) modem connected to a head-end system while the group of MT49R serves SLAVE units. In such an arrangement, the SLAVE units can be connected to any of the three phases, and the communication will be fully working.
