HD67C29-G43-E-B2 OPC UA Server to MQTT Broker converter with LAN, LTE Micro-SIM and internal eSIM

HD67C29-G43-E-B2 – industrial OPC UA Server / MQTT Broker converter, housing type B, DIN rail mounting, LAN and LTE connectivity (Micro-SIM + internal eSIM), fixed screw terminal block connectors.

HD67C29-G43-E-B2 is an industrial communication converter designed for projects where you need to connect the OPC UA world with an MQTT-based infrastructure. The device operates as an OPC UA Server, exposing data to OPC UA Clients, and at the same time it provides an embedded MQTT Broker, enabling MQTT publish and subscribe communication.

The G43 version is built for distributed deployments where mobile connectivity matters. This E variant adds an internal eSIM alongside the Micro-SIM slot, giving you more flexibility when selecting LTE connectivity for remote sites and long-term installations. It is a practical option for outdoor installations, temporary sites, containerized systems and mobile applications where fast commissioning is important.

The Ethernet RJ45 port is used for device programming and for MQTT and OPC UA communication. The interface provides one MAC Address for MQTT and one for OPC UA, which helps keep network diagnostics and traffic identification clear. For LTE transmission the device uses a cellular module and an SMA Female antenna connector (antenna with SMA Male).

The device provides:

• Electrical isolation between Ethernet and Power Supply
• Wide operating temperature range -40°C to +85°C
• Wide power supply range: 8…24V AC / 12…35V DC
• Consumption at 24V DC: 5 W
• 35 mm DIN rail mounting
• Industrial enclosure Modulbox 4M, type B with fixed screw terminal connectors

These parameters ensure reliable operation in demanding industrial environments.

HD67C29-G43-E-B2 is used in projects where you need to expose OPC UA data through an MQTT layer, while keeping communication available outside the local network thanks to LTE. The internal eSIM helps standardize deployments across many sites and reduces the operational overhead of SIM handling in the field.
