The F16V2 Differential Expansion Board connects the the F16V2/F16V2R via 40-pin ribbon cable. The board has 16 differential circuits that are accessed by four RJ-45 output connectors each with four circuits. This allows 16 strings to be located up to 250+ feet away from F16V2/F16V2R using 4 Differential Receiver Boards. Comes with 40-pin ribbon cable.
The 4-String Differential Receiver Board can be connected to the F16V2 Differential Expansion board allowing 4 strings to be placed up to 250+ feet from F16V2/F16V2R. The receivers have a 30amp voltage input connector. The input voltage can be 5V or 12V DC. Each output in rated at 5 amps.
