Serial port isolator, DIN-rail
The KD485-STD-xxx-xxx provides galvanic isolation between the two identical serial ports and the power input. The input and output port could be RS232 or RS422/485 on both sides.

Description
The KD485-STD-232-232 is an interface converter/isolator only and is baud rate and character format independent. Its main application is isolation between RS232 and RS232. It requires a power supply in the range of 7-35 volts at typically less than 2 watts. Port 1 is RS232, port 2 is RS232.
The KD485-STD-422-422 is an interface converter/isolator only and is baud rate and character format independent. Its main application is isolation between RS422 and RS422. It requires a power supply in the range of 7-35 volts at typically less than 2 watts. The KD485-STD-422-422 does not support RS485 because its interface drivers are permanently enabled, but can be used for RS485 monitoring. Port 1 is RS422, port 2 is RS422.
