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. Whether your environment is in the field, factory, or fire command center, "clean" or "noisy"*, CommFront's industry-proven opto-isolated converter products provide safe, reliable, simple, and cost-effective solutions for your data-conversion, distance-extension and device-protection applications. CommFront's product quality is ensured by our strict ISO 9001:2008 quality control system, and we back our high-quality isolators/converters with a 30-day risk-free money-back guarantee and a 5-year replacement warranty. Many companies boast ISO 9001 and other certifications, but few display their certification numbers to substantiate their claims. We are proud to provide our credentials to help our customers make a well-informed decision when choosing a long-term business partner.

* 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.
