DD20 - Data Distributor

Description

The DD20 has been designed to assist with the total integration of electronic equipment aboard a vessel. It accepts data from one source, either current loop, RS422 or RS232, and distributes it out 8x current loop outputs. Each output is capable of driving a number of current loop inputs, 8x RS422 outputs and 8x industry standard RS232 outputs. The unit is isolated from ground which provides full dc isolation between the input supply and ground/all outputs.
