PH232T485Y14
is a Bi-Directional RS-232 to 4 RS-485/RS-422 HUB that provides #4 RS-485/RS-
422 ports from one single RS-232 port that converts RxD & TxD signals of RS-232 standard to
differential (Data+ & Data-) signals of RS-485 standard and (RX+, RX- & TX+, TX-) signals of RS-422
standard at a same time. It works with Baud-Rate from 300bps to 230400bps. Using this device, you
can connect a RS-232 line, to 4 different devices which have RS-485 or RS-422 ports.
Since RS-485 is a Half-Duplex standard, switching between Transmit and Receive is done
automatically and further signals (such as RTS) are not required.
PH232T485Y14
supports Point-to-
Point and Point-to-Multi Point Party Line network topologies.
There are 3kV Optical and Electrical insulations have between RS-232/TTL UART and RS-485/422
sides, thus using this device in the RS-485/RS-422 line, can be very effective in eliminating electrically
and electromagnetically noises.
Protection against Surge, ESD and EMI is considered in its design, so,
PH232T485Y14
is good for
industrial usage and is useful for Industrial Automation, Telecommunications, SCADA Systems, DCS
Systems and …
