Industrial DMX to MQTT Broker converter with LTE, eSIM and VPN HD67C15-G43-E-VPN-B2

Industrial DMX to MQTT Broker converter with LTE, eSIM and VPN HD67C15-G43-E-VPN-B2.

HD67C15-G43-E-VPN-B2 is an industrial communication converter designed for secure integration of systems based on the DMX protocol with modern IoT platforms, SCADA systems and cloud applications using the MQTT Broker architecture. The device combines DMX data acquisition, cellular connectivity and encrypted communication within a single compact unit.

The G43-E-VPN version provides LAN and LTE connectivity with support for both a physical SIM card and an integrated eSIM, offering high flexibility in selecting mobile network operators. The built-in VPN service enables encrypted and protected data transmission over public cellular networks, ensuring confidentiality and integrity of communication between DMX installations and remote supervisory systems.

On the DMX side, the converter uses an RS-485 interface and supports data transmission at 250 kbps, fully compliant with the DMX protocol specification. MQTT communication is handled via the RJ45 Ethernet interface with 10/100 Base-T Autosensing as well as through the LTE cellular network. Galvanic isolation between Ethernet and the power supply improves resistance to electromagnetic interference and enhances operational safety in industrial environments.

The compact B2 Modulbox enclosure is designed for mounting on a DIN 35 mm rail. The device operates reliably in harsh industrial conditions and supports a wide operating temperature range from -40°C to +85°C. Its compact dimensions 70 × 60 × 95 mm allow installation in space-constrained control cabinets.
