USB TO 4CH Serial Converter - 4-channel USB converter - RS232/485/422/TTL

Description

The 4-channel USB to serial converter module is an invaluable tool for expanding and debugging a variety of industrial devices. It uses the original FT4232HL chip, which guarantees fast, stable and reliable communication and excellent compatibility. The module supports up to 4 channels of multifunctional serial ports. This is extremely convenient for extending or debugging various devices with a serial interface. Thanks to this module, you can adapt it to your needs by supporting TTL, RS485, RS422, as well as isolated RS232/485 ports. With built-in power isolation, it eliminates the need for an additional power source for isolated terminals. Additionally, it provides digital isolation, which translates into high reliability, immunity to interference and low energy consumption.

The converter is equipped with many protections, such as TVS (Transient Voltage Suppressor) to effectively suppress voltage spikes, which provides protection against lightning and ESD. Thanks to fuses and protective diodes, we can be sure of stable currents and voltages as well as protection against overvoltages and overcurrents, which affects the durability of the product. No-delay automatic relay system ensures fast and stable communication between the USB port and various interfaces without causing mutual interference. To facilitate monitoring and diagnostics, the board has 9 LEDs indicating the power supply and data transmission status.

The metal casing ensures not only solidity, but also nice appearance and the possibility of mounting on the wall. This USB converter is a tool that guarantees successful development and diagnostics of industrial devices. Thanks to it, you will gain control and reliability in your projects.
