HD67C31-B2 industrial IEC 61850 Server / MQTT Broker converter for IIoT data exchange

HD67C31-B2 – IEC 61850 Server / MQTT Broker converter in type B housing.

HD67C31-B2 is an industrial communication converter that links IEC 61850 Server environments with MQTT Broker architectures. It is a practical choice when you want to expose IEC 61850 data to modern publish/subscribe systems used in IIoT, monitoring platforms, analytics, or supervisory layers, while keeping an industrial-grade form factor and operating range.

The device uses a single Ethernet RJ45 port for programming and for MQTT and IEC 61850 communication. For deployment in cabinets and substations, it provides electrical isolation between Ethernet and power supply, DIN-rail mounting, and a wide power input range.

Product features

• IEC 61850 Server side combined with MQTT Broker integration for publish/subscribe data exchange.
• 1x Ethernet RJ45 used for programming and for MQTT and IEC 61850 communication.
• 10/100 Base-T Autosensing for both IEC 61850 and MQTT traffic.
• Electrical isolation between Ethernet and power supply for better resilience in noisy installations.
• Type B enclosure (Modulbox 4M) with B2 fixed screw terminals, designed for 35 mm DIN rail mounting.
• Two dedicated MAC addresses: one for the MQTT side and one for the IEC 61850 side, supporting structured network rollout.
• BTN1 Recovery Mode to recover the device after a wrong firmware update, with reset/update via the default IP address 192.168.2.206 using a webserver.
• MQTT payload templating supports the $VALUE$ keyword for inserting IEC 61850 values and extended keyword modes for multi-variable payloads.
