HD674-A010-2-E4V Industrial Modbus Slave to SNMP Manager Converter with 4kV Triple Isolation

HD674-A010-2-E4V – Industrial Modbus Slave to SNMP Manager Converter with triple 4kV galvanic isolation and rugged metal housing. 

The HD674-A010-2-E4V converter enables secure communication between Modbus RTU Slave devices and a SNMP Manager network. Designed for use in industrial, transport, and automation sectors, this gateway ensures stable data exchange even under harsh operating conditions. Its triple galvanic isolation (4kV) between the Modbus, SNMP, and power lines protects against voltage surges and EMI.

Thanks to its robust metal enclosure and vibration-resistant construction, the device is ideal for vehicles, trains, ships, and mobile or unstable environments. It supports two protection variants: IP65 with conformal PCB coating (version V), and IP67 with resin encapsulation (version R) for high resistance in humid and dusty installations.

The converter can be mounted on any flat surface (vertical, horizontal, oblique) using four integrated fixing lugs. Additionally, users can choose between Mini-Fit® or Superseal 1.5 connector types depending on installation preferences. Its extended temperature range from -40°C to +105°C meets automotive-grade requirements and ensures long-term operation even in extreme climates.
