INDUSTRIAL RS232 TO RS485 CONVERTERS
CommFront offers a range of rugged, industrial-grade, non-isolated (standard) or opto-isolated, port or externally-powered RS232 to RS485 converters. These industry-proven RS232 to RS485 converter products are professionally designed to interface with both commercial and industrial equipment, such as computers, PLC, RTU, SCADA, and HMI. Whether your environment is in the field, factory, or fire command center, "clean" or "noisy", these popular RS232 to RS485 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, spikes, transient surges, and remote lightning, which could potentially harm your expensive equipment such as computers and data communication devices. The CommFront opto-isolated RS232 to RS485 converters provide simple and effective ways to protect your devices from such potential damage. CommFront's product quality is ensured by our strict ISO 9001:2008 quality control system, and we back our high-quality RS232 to RS485 converters with a 30-day risk-free money-back guarantee and a 5-year replacement warranty.
