InLine 33307B serial converter/repeater/isolator USB 2.0 RS-232 Black

For interference-free serial data communication with galvanic isolation

Reliable protection against electrical interference:Galvanic isolation of up to 2.5 kV prevents a direct electrical connection between the USB and RS232 sides. This reduces ground loops, potential differences and interference. Easy connection of serial devices:The Converter connects computers with a USB-A interface to RS232 devices via a 4-pin screw terminal and provides a virtual COM port for existing software. Tried-and-tested FTDI chipset:The integrated FT232RNL chipset enables stable and reliable data transmission at baud rates from 300 to 921,600 b/s. High operational reliability:Integrated protection functions, including an isolated DC/DC converter, a 200 mA PTC fuse, ESD protection and TVS diodes, protect both the Converter and connected devices. Flexible for use in demanding environments:The wide operating temperature range of -40 °C to +85 °C, together with support for Windows 7, 8, 8.1, 10, 11, Linux, macOS and Android, enables versatile use.

The InLine® USB to Serial RS232 Converter with isolator connects modern computers with a USB interface to devices that still communicate via an RS232 interface. The connection is made via a 4-pin screw terminal and is provided as a virtual COM port, allowing existing applications to continue to be used without any modifications. The integrated galvanic isolation electrically separates the USB and RS232 sides from one another. This reduces potential differences, ground loops and electrical interference. This enhances operational reliability, particularly in environments with sensitive electronics or differing earth potentials. The FTDI FT232RNL chipset ensures reliable communication. In addition, an integrated isolated DC/DC converter, a 200 mA PTC fuse, ESD protection and TVS diodes protect the Converter and the connected devices. The Converter supports only the RS232 signals TX, RX and GND. The two GND connections are internally connected to each other and form the galvanically isolated RS232 ground. No other RS232 control signals are available via the screw terminals.
