Overview

The RS-232 Fiber Link Card system transports a full 9-Pin RS-232 copper signal over fiber optic cable. This fiber optic isolation system is an ideal solution for extending serial data communications over long distances or near large electrical equipment. Fiber optics provide long distance communication up to 74 mi. (120km) and immunity to EMI/RFI and potential transient surges which can cause noise or damage equipment.

The system supports asynchronous serial data rates from 50 bps to 1Mbit/s and has an auto-sensing feature that eliminates the need to manually set serial data rates. A comprehensive set of LEDs on the front panel indicate power status, fiber status, and serial data activity. The card supports 24-48VDC powering. RLH card housings have optional power supplies which support a wide range of power sources.

This rugged system is designed to operate over a wide operating temperature -40 to +70°C and compatible with all RLH card housings. This rugged system is manufactured in the U.S.A, and covered by our Limited Lifetime Warranty.
