HD67C12-G43-E-B2 – DALI to MQTT Broker converter with LTE and eSIM

Industrial DALI, DALI-2 to MQTT Broker converter with LTE and eSIM connectivity.

The HD67C12-G43-E-B2 is an industrial converter designed to integrate lighting systems based on the DALI standard with modern IoT platforms and BMS solutions using the MQTT protocol. The device operates as an embedded MQTT Broker, enabling bidirectional data exchange between the DALI bus and supervisory or cloud-based systems.

The G43-E version is equipped with an LTE module supporting both a physical SIM card and an integrated eSIM. This configuration provides high communication availability and flexibility, making the converter suitable for installations without permanent wired Ethernet infrastructure, such as distributed lighting systems and smart building applications.

The DALI interface is implemented via a 2-way 5 mm screw terminal block and operates at a data rate of 1200 bps, fully compliant with the DALI specification. On the network side, the converter provides 10/100 Base-T Autosensing communication via the RJ45 Ethernet port as well as data transmission over LTE.

Galvanic isolation between the Ethernet interface and the power supply improves resistance to electrical disturbances and increases operational safety in industrial environments. The compact B2 Modulbox enclosure allows fast installation on a DIN 35 mm rail.

The device is designed for operation in harsh environmental conditions, offering a wide operating temperature range from -40°C to +85°C. Compact dimensions of 70 × 60 × 95 mm allow installation in space-limited control cabinets.
