Single-Port Inline USB Isolator For Industrial And Medical Applications

Posted by Industry News on

SeaISO ISO-1 single-port inline USB isolator by Sealevel Systems, IncThe SeaISO ISO-1 single-port, inline USB isolator by Sealevel Systems, Inc. offers an easy-to-use method of protecting host and field equipment from damaging transients and surges commonly found in commercial, industrial and medical environments. The ISO-1 is UL Recognized, in accordance with EN60601-1 3rd Edition, and protects both the data and power lines with 4 kV of medical-grade isolation between the host control system and connected USB equipment.

The ISO-1 is USB bus powered, eliminating the need for external power. The efficient DC/DC design allows energy transfer over the isolation barrier. The isolator provides up to 300 mA to a downstream USB device when connected to a standard 500 mA USB port. Additionally, the isolator can provide a full 500 mA to a downstream device when connected to a USB port capable of sourcing 1 A, or greater. Convenient high-retention USB connectors prevent accidental cable disconnections.

Supported in Microsoft Windows, Linux, and other USB aware operating systems, the ISO-1 requires no separate drivers and is easy to install. Simply plug the isolator into an available USB port with the included cable, and it is automatically recognized as a generic USB hub device.

The ISO-1 is a USB 2.0 compatible device connecting to the host over a high-speed link and features full-speed (12 Mbps) data rates between the downstream USB device. The ISO-1 is housed in a rugged plastic enclosure with mounting ears that simplify mounting to walls, under counters, or inside panels.

RS232 to USB Converter With Arduino Due Or Mega 2560

Just about everyone who is involved with serial communication will have his/her RS232 to USB converter. Today's PCs don't even bother to support RS232. Consequently, a USB converter is mandatory to monitor RS232 data traffic. All this appears to render the following project obsolete. However, when it comes to a protocol converter, i.e. the conversion [...]
