Industrial #1 to #4 Serial RS485/RS422 HUB (Repeater & Isolator)


IP Electronix PH485Y14 is a 1 to 4 Serial RS485/RS422 Repeater Isolator Industrial HUB that provides #4 RS485/RS422 ports from one single RS485/RS422 port. It works with Baud-Rate from 300bps to 230400bps. Using this device, you can connect a RS485/RS422 line, to 4 different devices.

PH485Y14 can also be used as a RS485/RS422 Repeater and Amplifier. In addition, due to the fact that 3kV Optical and Electrical insulations have been used in the design of this device, this means all the ports are insulated from each other, so using this device in the RS485/422 line, can be very effective in eliminating electrically and electromagnetically noises. Also, the length of the RS485/RS422 line increases from 1200m to 2400m (1200m on each side).

Protection against Surge, ESD and EMI is considered in its design, so, PH485Y14 is good for industrial usage and are useful for Industrial Automation, Telecommunications, SCADA systems, DCS systems...
