HD67175-232-A1 Industrial Modbus RTU slave to SNMP manager converter with 4kV isolation

HD67175-232-A1 Industrial Modbus RTU slave to SNMP manager converter, housing type A (slim), DIN rail mount.

The HD67175-232-A1 is a compact industrial gateway designed to connect a Modbus RTU slave network to a SNMP manager environment, enabling seamless and bidirectional communication between OT and IT systems. Ideal for integration into SCADA, BMS, and industrial monitoring platforms, it ensures reliable communication over RS-232 serial and Ethernet interfaces. Thanks to its 3-way 4kV galvanic isolation between power, serial, and Ethernet lines, it offers excellent protection against industrial interference, voltage surges, and electromagnetic noise. Its compact type A housing allows installation in control cabinets with limited space, making it a reliable option for decentralized automation, remote equipment monitoring, and energy systems.

This converter supports up to 2000 bytes in reading and 2000 bytes in writing, allowing high-volume data exchange between field devices and SNMP-based infrastructure. Typical applications include data centers, HVAC plants, substations, and railway control systems where centralized management needs real-time access to Modbus slave registers. The device is fully configurable using the free SW67175 software, offering intuitive parameter definition, data mapping, and SNMP request assignment. With RJ45 Ethernet connectivity and a DE-9 serial port, it ensures fast deployment and compatibility with a broad range of controllers and legacy devices. The communication speed supports up to 115200 bps on Modbus RTU and auto-sensing 10/100 Mbps on SNMP.

Power supply flexibility is another major benefit of the HD67175-232-A1, accepting both 8–24VAC and 12–35VDC, which makes it adaptable for multiple industrial power schemes. Its wide operating temperature range of -40°C to +85°C allows deployment in harsh environments including outdoor enclosures, transportation vehicles, or energy facilities. The device is DIN rail mountable and lightweight (approx. 200g), with dimensions of 120 × 23 × 107 mm. Thanks to its robust design, reliable performance, and standards-compliant architecture, this converter is ideal for long-term industrial use where Modbus and SNMP need to be transparently bridged.
