HD674-A009-4-E4V Industrial Modbus Slave to SNMP Agent Converter with 4kV Isolation

HD674-A009-4-E4V – Industrial Modbus Slave to SNMP Agent Converter with reinforced 4kV isolation and ruggedized housing. 

The HD674-A009-4-E4V is a highly reliable Modbus RTU Slave to SNMP Agent converter designed for harsh industrial and automotive environments. This industrial-grade device ensures robust protocol translation while maintaining secure communication between a Modbus master device (such as PLC, SCADA or HMI) and SNMP-based monitoring systems.

Thanks to its triple 4kV galvanic isolation – between Modbus/Power, SNMP/Power, and Modbus/SNMP – the converter guarantees maximum protection against electrical disturbances and voltage surges, a key requirement in mission-critical installations.

The converter is housed in a metal enclosure resistant to vibration and shock, ideal for use in vehicles, ships, railways, automation cabinets and unstable environments. Two versions are available: V-version (IP65) with PCB coating for dust protection, and R-version (IP67) with resin encapsulation for enhanced insulation and humidity resistance. Users can choose between Mini-Fit or Superseal 1.5 connectors depending on mechanical and cabling requirements.

It operates over a wide temperature range from -40°C to +105°C, meeting stringent AUTOMOTIVE and INDUSTRIAL standards. The DIN-rail mount option combined with flexible mounting surfaces (horizontal, vertical, or oblique) allows seamless integration in tight or constrained environments.
