Overview

The FRM220-CCF contact closure fibre converter comes in two versions, one with 2 channels (CCF20) and one with 4 channels (CCF40) and provides transmission of contact closure over a single fiber optic link. An SFP slot provides for a wide variety of fibre options - multi-mode and single-mode, as well as BiDi which allows bi-directional transmission using only a single fiber core. The FRM220-CCF has contact inputs and 0.5 amp contact output relays. The relay output follows the “relay input” from the remote end. When the remote “relay input” is shorted, the local relay output is closed and vice-versa. Any one of the relay outputs can be configured to close when “carrier loss” is detected from the remote end. (Either through a CH01M console or via NMCin managed chassis.) Carrier Loss indicates that the optical fibre is disconnected or that the remote end has lost power and is not operating. This "carrier loss" relay can then be connected to an appropriate alarm circuit.
