INDUSTRIAL OPTO-ISOLATED SERIAL CONVERTERS

CommFront offers a range of rugged, industrial-grade, port or externally-powered RS232/RS422/RS485 isolators and opto-isolated USB/RS232/RS485/RS422 Converters and Hubs. The CommFront opto-isolated converters and isolators provide simple and effective ways to protect your expensive devices from potential harms including ground loops, transient surges, remote lightning, and spikes - regardless whether your environment is in the field, factory, or fire command center, "clean" or "noisy"*. CommFront opto-isolated converter products were strictly certified by SGS/TUV (the Nationally Recognized Testing Laboratories [NRTLs] in North America (approved by OSHA) and the Notified Bodies in the European Union. CommFront's product quality is ensured by our ISO 9001:2008 (strictly certified by SGS/UKAS) quality control system and we back our high-quality fiber optic converter products with a 30-day risk-free money-back guarantee and a 5-year replacement warranty.

* A "noisy" environment is an area surrounded by ground loops, spikes, transient surges, and remote lightning, which could potentially harm your expensive equipment such as computers and data communication devices.
