Serial RS232/TTL USART Repeater & Isolator


IP Electronix PH232Y11 is a Bi-Directional Serial RS232/TTL UART Repeater and Isolator and Amplifier. It works with Baud-Rate from 300bps to 230400bps. This device adds up to 3kV optical and electrical insulation between the two RS232 sides, which eliminates noise from the RS232 path. Also, if a length of more than 15m is required for the RS232 line, by adding one PH232Y11, the length of the RS232 cable can be increased up to at least 30m, i.e., 15m meters on each side. Also, due to having the TTL ports, PH232Y11 can be connected directly to a microcontroller system.

Protection against Surge, ESD and EMI is considered in its design and also there is 3kV Electrical and Optical insulation between RS232/TTL UART sides.

PH232Y11 is designed for industrial usage and is useful for Industrial Automation, Telecommunications, SCADA Systems, DCS Systems and …
