HD67C12-G43-B2 – DALI to MQTT Broker converter with LTE for BMS and IoT

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

The HD67C12-G43-B2 is an industrial converter designed to integrate lighting systems based on the DALI standard with modern IoT platforms and BMS systems using the MQTT protocol. The device operates as an embedded MQTT Broker, enabling publishing and subscription of DALI data in supervisory systems, cloud applications and analytical platforms.

The G43 version is equipped with an LTE module and a SIM card slot, allowing independent communication in locations without permanent Ethernet infrastructure. This makes the converter well suited for distributed lighting installations, smart buildings and energy management systems.

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 standard. 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 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.
