In industrial environments it is often necessary to use a higher grade of quality and toughness to avoid communication issues and to withstand damage by harsh environments. This is where the USC-WUSB232B comes in. This is an industrial grade USB to RS232 / RS485 converter with DIN mount and optional screw mounts. It has screw terminals for the RS232 / RS485 side for easy connection of single wires and a standard female USB type B connector on the USB side. LED indications lights for power, TX and RX makes it easy to see the converter is powered and when data is flowing.
This USB to RS232 / RS485 converter is designed around the reliable FT232RNL processor from FTDI, which makes it a high performance, fast and very reliable converter for most applications.
The converter gets its power from the USB port so no external power is needed. The power provided from the USB port is isolated from the data signals for effective protection of the connected serial device and to prevent data loss. Built-in digital isolation, transient voltage suppressors (TVS), a self-recovering fuse and protection diodes, effectively suppresses voltage surges, transient voltage spikes, static electricity and over voltages/current.
A built-in 120 ohms terminal resistor on the RS485/RS422 ports is configurable by a jumper.
