HD674-A027-E4V isolated DMX to Modbus TCP Slave converter with rugged metal housing

Industrial isolated DMX to Modbus TCP Slave Converter, metal housing resistant to vibration and shock with triple 4kV isolation between DMX/Modubs TCP, DMX/power supply and Modbus TCP Slave/power supply.

The HD674-A027-E4V is a robust DMX to Modbus TCP Slave converter designed for highly demanding environments where reliable communication and mechanical resistance are essential. With its metal housing resistant to vibrations and shocks, the device is particularly suited for mobile and industrial applications such as cars, trucks, trains, boats, or heavy industrial machinery. Thanks to its triple galvanic isolation 4kV (between DMX/Modbus TCP, DMX/power supply, and Modbus TCP/power supply), the converter ensures maximum safety, noise immunity, and long-term operational stability. It is an excellent solution wherever DMX512 lighting systems need to be integrated into Modbus TCP-based control infrastructures.

Two specific versions are available to meet environmental requirements: the V-version with PCB coating ensures complete protection against dust and solid particles (IP65), while the R-version with resin encapsulation provides IP67 protection, making the unit suitable for wet or highly humid conditions. This version also enhances noise resistance, which is crucial in automotive and transportation applications where electrical disturbances are frequent. Both designs maintain compact dimensions and are manufactured to withstand long-term exposure to industrial-grade conditions.

The device can be mounted on any surface orientation (horizontal, vertical, or oblique) using its four fixing lugs, offering flexibility for installers. Users can also choose between Mini-Fit® or Superseal 1.5 connectors, depending on their preferred wiring standard. With an operating temperature range of -40°C to +105°C, the HD674-A027-E4V is perfectly aligned with automotive-grade requirements. This extended range ensures functionality both in extremely cold climates and in environments where equipment is exposed to high levels of heat. Together, these features make the unit ideal for OEM integrators, industrial automation engineers, and lighting system designers.
