The RS232<=>RS232 galvanic separator is used to galvanic separation of TX, RX, RTS and CTS lines (for the RS-232<7>RS-232 separator also DSR, Carrier Detect) of the RS-232C interface and it ensures correct communication with speed of 116kbites/sec. The maximum level of separation voltage is 1000 V DC (700 V AC 50Hz). The signal lines are protected against over-voltage and the static charges by means of semiconductor protectors. The voltage levels are similar to the requirements of the RS232 standard (about 9V with supply voltage of 5V). Low power consumption enables a flexible choice of the source of supply (e.g. from the USB port of a PC computer).

Apart from standard usage, the separator can be used wherever there is need of separation of ‘ON/OFF’ type signals (including voltage levels on the separator’s lines). Then there can be used four one-way lines: two one-way (TX, RTS) and two the other way (RX, CTS) or seven one-way lines: three one-way (TX, RTS, DTR) and four the other way (RX, CTS DSR, Carrier Detect) in the RS-232<7>RS-232 separator.
