HD67C32-G43-B2 industrial IEC 61850 Client to MQTT Broker converter with LTE connectivity

HD67C32-G43-B2 – IEC 61850 Client / MQTT Broker Converter with LAN and LTE SIM.

HD67C32-G43-B2 is an industrial communication converter that reads data as an IEC 61850 Client and publishes it to an MQTT Broker. It is built for IIoT data pipelines, telemetry and monitoring layers where IEC 61850 needs to feed modern publish/subscribe applications without adding complexity on the PLC/SCADA side.

The G43 variant adds LTE connectivity for remote and distributed installations. LTE uses a physical Micro-SIM and an SMA Female antenna connector (the antenna must have an SMA Male connector), so you can keep MQTT communication available even when a permanent wired connection is not practical.

Product features

• IEC 61850 Client on the field/energy side combined with MQTT Broker integration for publish/subscribe data exchange.
• LAN + LTE Micro-SIM in the G43 version for installations that require cellular connectivity.
• 1x Ethernet RJ45 used for programming and for MQTT and IEC 61850 communication.
• 10/100 Base-T Autosensing data rates for IEC 61850 and MQTT traffic.
• Electrical isolation between Ethernet and power supply to improve resilience in noisy industrial environments.
• 35 mm DIN rail mounting, enclosure type B (Modulbox 4M), connector type B2 (fixed screw terminal).
• Two dedicated MAC addresses: one for the MQTT side and one for the IEC 61850 side, supporting structured network deployment.
• MQTT payload templates support $VALUE$ for single-variable topics and keyword-based multi-variable payloads (useful for JSON structures).
• BTN1 Recovery Mode for recovery after a wrong firmware update; firmware update or reset is possible via default IP 192.168.2.206 using a webserver.
