A1MB
A1/Modbus converter
A1MB
DIN-sized protocol convertor which makes Smart meter A1 measurement values available by Modbus.
The Xemex’s A1MB module is a DIN-sized converter module, converting Smart Meter A1 messages to Modbus over RS485 messages.
The module supports A1 ports defined according DSMR4 and DSMR5 specification. The A1MB is connected to the A1 port of the Smart Meter via a cable with RJ11 connectors on both ends. The Modbus of the module is connected via 3-wires to the RS485 (A(+), B(-) and S), acting as slave device to a Modbus master.
The unit will be powered via the power present on the A1 port of the Smart Meter. External power supply, via external power adapter, can be added optionally should that be required.
