HD67C25-G43-E-VPN-B2 SNMP Agent MQTT Broker converter with VPN (LAN + LTE SIM + eSIM)
HD67C25-G43-E-VPN-B2 is an industrial SNMP Agent / MQTT Broker converter with an integrated VPN service and mobile connectivity based on LAN + LTE. This version combines a physical micro-SIM slot with a built-in eSIM, so you can design reliable telemetry and remote monitoring deployments even where wired infrastructure is limited or where you need redundancy in the field.
In practice, HD67C25-G43-E-VPN-B2 helps you connect classic SNMP environments (industrial networks, OT monitoring, legacy supervision tools) with modern MQTT ecosystems used in IIoT platforms, dashboards, and analytics. You can map SNMP data to MQTT topics and build a clean data flow from machines, panels, and infrastructure to your server or cloud, while keeping the communication protected by VPN.
HD67C25-G43-E-VPN-B2 key benefits for industrial and IIoT projects
- VPN service for secure remote access and protected data transport in distributed installations.
- LAN + LTE connectivity with micro-SIM and built-in eSIM to simplify logistics and increase uptime in remote sites.
- SNMP Agent and MQTT Broker functions in one device for clean integration between OT and IT layers.
- Electrical isolation between Ethernet and power supply to improve robustness in industrial cabinets.
- Wide operating range: -40°C to +85°C and wide power input (8 to 24V AC, 12 to 35V DC).
- DIN rail mounting in housing type B (Modulbox 4M) for fast panel installation and maintenance.
Typical applications for HD67C25-G43-E-VPN-B2
HD67C25-G43-E-VPN-B2 is commonly selected for factories, utilities, water and wastewater, energy sites, building infrastructure, and OEM telemetry projects where SNMP monitoring must be extended to MQTT systems. It fits both new deployments and upgrades, especially when the installation requires mobile connectivity and secure access without exposing the OT network.
Configuration and commissioning
To configure HD67C25-G43-E-VPN-B2, use the dedicated Windows software Compositor. With it you can define MQTT parameters, SNMP line parameters, the list of allowed MQTT clients, and the topic lists published/subscribed between MQTT and SNMP managers. The Ethernet port is also used for programming and for MQTT/SNMP communication via standard RJ45 10/100 Base-T connection.
