This Industrial Serial Data DIN Fiber Link system transports a full 9-PIN RS-232 copper signal over fiber optic cable. This 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. Powering options include standard 24-48VDC or high range DC powering of 125VDC. This rugged system is designed to operate over a wide operating temperature -40 to +70°C and features are dual redundant power inputs, and a system alarm relay for maximum uptime and reliability. Included is a DIN clip and wall mount ears for easy installation into to a wide range of environments.
