HD67165-232-A1 Modbus RTU slave to SNMP agent converter for DIN rail

Industrial Modbus RTU slave to SNMP agent converter – type A housing (slim), DIN rail mount.

HD67165-232-A1 is a high-reliability industrial protocol converter designed to interconnect Modbus RTU Master networks (e.g. PLCs, SCADA systems, HMI panels) with SNMP Manager systems (e.g. supervisory PCs, IT management platforms) for seamless bi-directional data exchange. This device allows you to transparently transmit and receive information between two otherwise incompatible network layers, enabling real-time process monitoring, diagnostics, and control from SNMP-based systems over Ethernet.

Its compact type A housing (only 23 mm width) and DIN rail mounting make it a perfect choice for installations where panel space is limited. Combined with its wide power input range (8–24VAC or 12–35VDC), it can be easily deployed in industrial cabinets, automation panels, or remote telemetry units without needing additional power converters or custom hardware adjustments.

HD67165-232-A1 is ideal for industrial automation, smart buildings, energy monitoring, HVAC systems, and IT infrastructure, bridging the gap between OT (Operational Technology) and IT. Whether you need to publish Modbus sensor data to SNMP managers or access real-time alarm states from a PLC network, this converter delivers robust, reliable communication for your project.

Configuration:

The device can be easily configured through the free SW67165 software provided by the manufacturer. Using this software, the user can:

• Set SNMP parameters including community strings and object mappings,
• Configure Modbus line parameters such as baud rate, parity, stop bits, etc.,
• Create data maps between Modbus registers and SNMP OIDs,
• Update the firmware or load new configuration profiles,
• Use built-in tools for diagnostics and communication testing.

No license is required to use the configuration software, which is compatible with Windows systems.
