M-Bus Master / Modbus TCP Slave – Converter HD67044

These converters are contained in a metal housing, so it is STRONG and RESISTANT to the vibrations and shocks. The electrical parts are with triple isolation of 4000 V between Ethernet/Serial – Ethernet/Power Supply – Serial/Power Supply. Particularly suitable for the installation on cars, trains, boats, industrial sector and in fragile environments. Two versions, one with Varnished PCB and one with Resined PCB. Varnished treatment gives dust and humidity protection, Resined treatment gives high water, dust and vibrations protection. Excellent range of temperature resistance from -40 C to +105 C, features required by AUTOMOTIVE applications.
