Transport 2 Active Channels of Serial Data Over Fiber
The RLH Serial Data DIN Fiber Link system transports two active channels of copper serial data over fiber optic cable, allowing for both RS-232 and RS-485/422 to be used at the same time. Fiber optics not only provide long distance communication up to 74 mi. (120km), but also provide immunity to EM/RFI and transient surges. This is ideal for extending serial data communications over long distances, or near large electrical equipment where resistance to EMI is desired.
A comprehensive set of LED’s on the front panel indicate power status, fiber status, RS-232 and RS-485/422 activity. Powering options include our standard 24-48VDC, or high range DC powering of 125VDC. This rugged system also features redundant power inputs with a system alarm contact, and comes standard with DIN clip and wall mount ears.
