HD67C30-G43-E-B2 industrial Ethernet / MQTT Broker converter with LTE SIM and eSIM

HD67C30-G43-E-B2 – Ethernet / MQTT Broker converter with LAN, LTE SIM and eSIM.

HD67C30-G43-E-B2 is an industrial communication converter that bridges Ethernet and an MQTT Broker, enabling data publishing/subscribing for IIoT platforms, remote monitoring, automation and BMS. It is built for 24/7 operation in harsh environments, with electrical isolation and an extended operating temperature range.

The G43 variant includes an LTE module with a Micro-SIM slot and an SMA Female antenna connector (the antenna must have an SMA Male connector). The E option adds an internal eSIM for LTE connectivity managed from ADFweb’s platform, which is useful when you need fast rollout across multiple sites or you want to simplify SIM logistics.

Product features

• Ethernet / MQTT Broker conversion for industrial automation and IIoT data exchange.
• LAN + LTE SIM + eSIM connectivity options for remote and distributed installations.
• Electrical isolation between Ethernet and Power Supply for improved robustness in noisy environments.
• 35 mm DIN rail mounting, enclosure type B (Modulbox 4M), connector type B2 (fixed screw terminal).
