Powerline modems
with RS232/RS485 interface for 230 / 400 V networks
Key feautures
Typical application
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.
