AMCV M4x, Mesh/RS485 converter

Converters Mesh/RS485 of AMCV M4x type are designed for collection of data from electricity meters in the distribution network equipped with RS485 interface and for their subsequent sending to the Mesh network.

Properties

  • Converters are parameterized by the manufacturer. They can be set as:
    router  - connected to a gateway of type AMCV M4-CG or AMCV MU-CG,
    gateway – allows data collection via router;
  • Possibility to set 17 parameterizable channels, the manufacturer sets the address, frequency, transmission power and baud rate;
  • Four indicator LEDs on the front panel, which in addition to the connection to the gateway also indicate the signal strength;
  • Pulse input for connecting devices with open connector or relay contact;
  • The converters are manufactured in accordance with the standards IEC/EN 300 220, IEC/EN 301 489, IEC/EN 60950, IEC/ЕN 62056-21, IEC/EN 62056-61 and according to requirements of EU Directive for R&TTE.
