Industrial Opto-Isolated Serial Converters
CommFront offers a range of rugged, industrial-grade, port or
externally-powered RS232 isolators and opto-isolated USB / RS232 /
RS485 / RS422 Converters and Hubs. These industry-proven, opto-isolated
serial converter products are designed to interface with
mission-critical equipment, such as computers, PLC, RTU, SCADA and HMI.
Whether your environment is in the field, factory, control room, or
fire command center, "clean" or "noisy", these popular opto isolated
converter products provide safe, reliable, simple, and
cost-effective solutions for your data-conversion and
device-protection applications. * A "noisy" environment is an area surrounded by ground loops, transient surges, remote lightning and spikes, which could potentially harm your expensive equipment such as computers and data communication devices. The CommFront opto-isolated converters and isolators provide simple and effective ways to protect your devices from such potential harms. CommFront's product quality is ensured by our strict ISO
9001:2008 quality control system, and we back our high-quality opto-isolated
serial converters with a 30-day risk-free money-back guarantee and
a 5-year replacement warranty.

3-Wire Industrial Port-Powered RS232 Isolator
The CVT-232A-3 is a compact, industrial-grade, port-powered RS-232 isolator. The unit optically isolates three (3) RS-232 lines (TX, RX and GND), which effectively protects your RS-232 devices from ground loops, transient surges, remote lightning and spikes. The 5000V optical isolation also eliminates ground loop and noise problems. The unit is efficiently powered from the RS-232 data line, and therefore, no external power, software drivers or RTS, DTR is required.
