HD67C29-G43-VPN-B2 OPC UA Server to MQTT Broker converter with LTE SIM and VPN service

Industrial OPC UA Server / MQTT Broker converter with built-in VPN service, housing type B, DIN rail mounting, LAN and LTE SIM connectivity.

HD67C29-G43-VPN-B2 is an industrial communication converter designed for projects where you need to connect the OPC UA world with an MQTT Broker-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 key differentiator of HD67C29-G43-VPN-B2 is the integrated VPN service, enabling encrypted remote access to the infrastructure and process data. Combined with LTE connectivity using a Micro-SIM card, this variant is well suited for distributed automation systems, mobile installations and sites without fixed wired connectivity.

The device uses the Ethernet RJ45 port for 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. The G43 version includes 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.
