The SEH INU-50 is an industrial deviceserver from the brand SEH, model type INU-50, with manufacturer number M07220. It enables the integration of USB devices as well as serial RS-422/RS-485 devices into a Gigabit Ethernet network. The device is designed for use in demanding industrial environments where reliable and stable network connectivity of peripheral devices is required, such as in production facilities, automation systems, or building automation.

Applications
The INU-50 is suitable for applications where USB or serial devices need to be accessed over a network without requiring physical connections to each device. Examples include remote control of printers, barcode scanners, measuring instruments, or industrial sensors. Integration is achieved via a Gigabit Ethernet network, making the devices accessible from any endpoint on the network. The DIN rail mounting allows for flexible integration into existing enclosures and control systems.

Functions and Features in Detail
The deviceserver features two USB 2.0 HighSpeed ports, enabling a maximum data transfer rate of up to 25 MB/s for a connected device. This ensures fast and seamless data transmission, especially for devices with high data volumes. Additionally, it includes a serial RS-422/RS-485 port, suitable for communication with older or specialized industrial devices. The serial interface supports robust data transmission over long distances and is resistant to interference.

Technology Explained Simply
The INU-50 acts as a network bridge between physical devices and an Ethernet network. It allows USB and serial devices to be addressed over the network as if they were directly connected to a computer. Communication is established via an RJ-45 network port, supporting Gigabit Ethernet (1000Base-T), ensuring high data transfer rates and low latency. The redundant power supply operating in the voltage range of 12 to 24 V enhances availability, as the device can continue operating even if one power source fails. The operating temperature ranges from −20 °C to +60 °C under full load on both USB ports, and up to +70 °C under low load, enabling use in environments with varying climatic conditions.

Compatibility and Accessories
The INU-50 is compatible with USB 2.0 HighSpeed devices and RS-422/RS-485 serial devices. It can be integrated into existing Gigabit Ethernet networks. No specific accessories are included in the delivery scope; mounting is done using the standardized 35-mm DIN rail according to DIN EN 60715. No additional accessories or adapters are included.

Mounting and Installation
Mounting is performed via DIN rail mounting on a 35-mm DIN rail, commonly used in industrial enclosures. Installation requires no special tools; the device is simply clipped onto the rail. Network connection is made using a standard Ethernet cable (RJ-45), and power supply is provided via a corresponding 12–24 V power supply (not included). Configuration is done via network protocols, with detailed instructions provided in the technical documentation.

Operational Advantages
Using the INU-50 reduces the need for physical cable connections between devices and control systems. This simplifies installation and maintenance and increases flexibility in device placement. The redundant power supply and robust construction ensure high availability, especially in critical applications. Support for USB 2.0 HighSpeed and RS-422/RS-485 extends compatibility with a wide range of devices. The operating temperature range allows use in diverse environments, from air-conditioned rooms to industrial halls with high temperatures.
