HD674-A010-4-E4V Industrial Modbus Slave to SNMP Manager Converter with 4kV Isolation

HD674-A010-4-E4V – Industrial Modbus Slave to SNMP Manager Converter with 4kV Galvanic Isolation and IP65/IP67 protection. 

The HD674-A010-4-E4V is a high-performance industrial converter that enables seamless communication between a Modbus RTU Slave network and a SNMP Manager system. Designed for use in rugged and mobile environments, this device ensures reliable data exchange even in the presence of strong EMI interference. Its triple 4kV galvanic isolation between the interfaces (Modbus, SNMP, and power supply) provides outstanding protection against voltage spikes and disturbances. The converter ensures stable operation in high-noise installations such as rail transport or factory automation. It is compliant with industrial safety standards and helps prevent cross-interface surges. Communication reliability is increased through microprocessor-based signal validation, reducing the risk of false data transfers.

With its rugged metal housing, the converter is resistant to vibration, shock, and harsh industrial conditions. The device is available in two protective versions: V (IP65) with PCB coating for dust protection and R (IP67) with resin encapsulation for humidity and acoustic resistance. It supports flexible installation on horizontal, vertical or inclined surfaces using four fixing lugs and allows connector selection between Mini-Fit or Superseal 1.5, depending on the installation. The metal enclosure prevents mechanical stress from affecting internal circuits, ensuring longer device life. With anti-corrosive properties and optional hose clamp mounting, it's ideal for exposed environments. The choice of connectors allows compatibility with existing wiring infrastructure in various transport and factory control systems.

The supported temperature range from -40°C to +105°C meets the requirements of the AUTOMOTIVE sector. Its design guarantees durability and uninterrupted operation in dynamic and extreme climate environments. The model is ideal for installations in trucks, trains, ships, and heavy-duty industrial vehicles. This thermal tolerance ensures protection against seasonal temperature shocks, including freezing or desert climates. The converter’s components are selected for continuous 24/7 operation without thermal fatigue. It offers consistent performance even during engine startup spikes or HVAC load cycles in mobile platforms.
