USB To Isolated RS-232/422/485 - 4 Port
The first truly “rugged” USB to serial converter
Our USR602 and USR604 industrial grade, isolated, USB to Asynchronous Serial Protocol Converters allow you to add up to four RS-232, RS-422, or RS-485 ports to your PC. The rugged design provides 2 kV isolation between the serial ports and the USB port. Additional features such as a heavy duty metal enclosure with panel and DIN Rail mounting options, high ESD protection, shock and vibration testing, and wide operating temperatures, make them well suited for harsh environments and use in instrumentation, utility, and laboratory applications. They are UL Class 1 Division 2 Listed for used in hazardous locations.
The USR602 and USR604 are packaged in a rugged metal housing. The serial ports are configurable for RS-232, RS-422 and RS-485 (2-Wire & 4-Wire) at speeds up to 921.6 Kbps. Modbus support enables them to be used with a wide variety of industrial devices. USB Connectivity is provided through USB 2.0 Type B High Retention Connector with 3.2 lbs.-force minimum disconnect strength. 10 to 48 VDC power is supplied through a removable three position terminal block. There is an additional threaded barrel connector if your application requires an AC power adapter such as our PS12VLB-INT-MED. USB driver software is included on CD ROM or can be downloaded from this web site. The drivers support Windows Operating Systems up to Windows 8 (32 and 64 bit).
