FVR21-LV Comnet Dual Video Receiver With Manual Gain, mm, 2 fiber with Video Loss Relay

The ComNet FVR21-LV dual video receiver detects two independent AM video signals in one module on two independent multimode fiber optic cables. The module is not a multiplexer. The unit incorporates a “Loss of Video” relay for each channel. Upon loss of video signal or optical fiber break, the normally closed relay opens. The module is ideal for CCTV installations and the rack mount version can be used to double the fixed video capacity of the C1 rack for up to 28 independent video channels per card cage. The modules utilize Manual Gain Control. The receiver is compatible with the ComNet FVT11M and the FVT20 dual video transmitter. Plug-and-play design ensures ease of installation. Bi-color (Red/Green) LED indicators are provided for rapidly ascertaining equipment operating status. Packaged in the exclusive ComNet ComFit housing, these units may be either wall or rack-mounted, or may be DIN-rail mounted by the addition of ComNet model DINBKT1 adaptor plate.
