ISO-232-3P9: 5000V Port-Powered Optically Isolated RS232

Industrial serial networks require strong surge defense. The ISO-232-3P9 delivers 5000V optical isolation across TX, RX, and ground lines to shield connected hardware from high-voltage spikes and destructive ground loops. Operating at baud rates up to 912,600 bps, this bi-directional DB9 serial module draws power directly from standard data lines, eliminating the need for bulky external power supplies. Built-in 600W surge suppression and 15KV ESD protection keep noise-sensitive automation lines stable in extreme environments.  Unexpected signal ground currents ruin sensitive serial equipment. Florida Circuit sources authentic ISO-232-3P9 modules directly through fully vetted supply channels, guaranteeing genuine hardware for your field deployments.
