The 4 Wire Analog Data fiber link card provides a transmission of 2/4-wire data signal over two optical fibers, and supports full duplex constant transmission up to 9600bps (9.6Kbps) in voice-frequency or audible tone range (300Hz-3.4KHz). 2-wire data is half duplex, and 4-wire data is full duplex. Common applications include SCADA and protective relay systems.
Note: CO and Sub 4-wire Data cards are electronically identical and may be interchanged except when the simplex current output option is ordered on the Sub card.
This fiber link card is designed to be installed into any of the RLH Fiber Link Card Housings, and occupies a single card slot.
