Functional Description

The I-7551 Photo coupler provides a complete full-duplex (including control signal) electrical isolation channel between two RS-232 devices. This isolation is an important consideration if a system uses different power sources, has noisy signals or must operate at different ground potentials.

The I-7551 has the option of reconfiguring which control signal is used. CTS can be selected instead of DCD and RTS instead of DTR.

The I-7551 incorporates two DC-to-DC converters, the isolation site of I-7551  is located in the input and output interface circuit. In other words, I-7551 is three- way isolation RS-232 to RS-232 converter.
