HD67C25-G43-E-B2 SNMP Agent to MQTT Broker Converter with LTE eSIM DIN Rail

Industrial SNMP Agent / MQTT Broker converter with LAN, LTE and eSIM connectivity, type B housing, DIN rail mounting.

HD67C25-G43-E-B2 is an industrial communication converter designed to integrate systems operating in SNMP environments with infrastructures based on MQTT Broker. The device operates as an SNMP Agent, making internal data available to SNMP Managers while simultaneously supporting MQTT-based communication.

The HD67C25-G43-E-B2 features an Ethernet RJ45 port, LTE connectivity via SIM card and integrated eSIM, ensuring flexible deployment in distributed industrial environments. Mobile connectivity enables reliable data transmission in locations without permanent wired internet infrastructure.

The converter enables:

• Operation as an SNMP Agent
• Publishing and subscribing MQTT topics via embedded MQTT Broker
• Definition of authorized MQTT clients
• Creation of publish and subscribe topics
• Mapping SNMP variables into MQTT payload structures
• Integration with SCADA, BMS and Industrial IoT platforms

Both SNMP and MQTT communications support 10/100 Base-T Autosensing data rates.

Industrial-grade design ensures:

• Electrical isolation between Ethernet and power supply
• Wide power supply range 8…24V AC / 12…35V DC
• Wide operating temperature range -40°C to +85°C
• DIN rail mounting (35 mm)
• Modulbox 4M industrial housing type B

These characteristics guarantee reliable performance in demanding industrial conditions.

The device includes four diagnostic LEDs indicating:

• Device status
• SNMP communication
• MQTT Broker communication
• Error status

A dedicated Recovery button allows restoring service mode in case of configuration errors.

The Ethernet port is used for configuration and for SNMP and MQTT communication. The LTE module supports Micro-SIM and integrated eSIM, providing flexible and redundant mobile connectivity options.
