Serial RS232/RS485/RS422 Converter, Repeater & Isolator


IP Electronix PH232T485Y11P is a Bi-Directional Serial RS232/RS485/RS422 Converter, Repeater and Isolator that converts RxD & TxD signals of RS232 standard to differential (Data+ & Data-) signals of RS485 standard and (RX+, RX- & TX+, TX-) signals of RS422 standard at a same time. It works with Baud-Rate from 1200bps to 921600bps

Since RS485 is a Half-Duplex standard, switching between Transmit and Receive is done automatically and further signals (such as RTS) are not required. PH232T485Y11P supports Point-to-Point and Point-to-Multi Point Party Line network topologies.

There are 3kV Optical and Electrical isolations have between two sides, thus using this device in the RS232/RS485/RS422 line, can be very effective in eliminating electrically and electromagnetically noises.

Protection against Surge, ESD and EMI is considered in its design, so, PH232T485Y11P is good for industrial usage and is useful for Industrial Automation, Telecommunications, SCADA Systems, DCS Systems and …
