HD67C27-G43-E-VPN-B2 PROFINET Master to MQTT Broker converter with LTE eSIM and VPN

Industrial PROFINET Master / MQTT Broker converter with built-in VPN service, housing type B, DIN rail mounting, LAN and LTE connectivity (Micro-SIM + internal eSIM).

HD67C27-G43-E-VPN-B2 is an industrial communication converter designed to integrate PROFINET networks where the gateway operates as a PROFINET Master with systems based on an MQTT Broker. It enables stable delivery of process data from PROFINET to higher-level systems, IoT platforms and analytics applications, both on a local Ethernet network and in remote deployments.

A key advantage of HD67C27-G43-E-VPN-B2 is the integrated VPN service, providing encrypted remote access to infrastructure and process data. Combined with LTE connectivity (Micro-SIM and built-in eSIM), the converter supports secure communication in distributed automation systems, mobile installations and sites without fixed wired Internet access.

The device uses a single Ethernet RJ45 interface for both PROFINET and MQTT, and it exposes separate MAC addresses for the MQTT and PROFINET functions, making network integration and diagnostics clearer. On the mobile side, the G43 version uses an LTE module with 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
• 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.
