RS-485/RS-422 Repeater and Isolator

INTRODUCTIONRS-485 Repeater and Isolator

IPEX PH485RPX™ is a RS-485 and RS-422 Repeater and Isolator. If it is needed to have RS-485/RS-422 network with length more than 1200m or to have more than 32 nodes, using a PH485RPX™ helps you to increase the network length up to 2400m and also to have up to 64 devices connected to it. PH485RPX™ is compatible with RS-485 standard devices differential Data+ & Data- signals and is fully Plug & Play. It works with a wide range of +8V up to +48V DC power supply with low (about 45mA) consumption.  PH485RPX™ is designed for industrial usage and is useful for Industrial Automation, Telecommunications, SCADA Systems, and DCS Systems …

Protection against Surge, ESD and EMI is considered in its design and also has 3kV isolation between RS-485/RS-422 sides. Since RS-485 is a Half-Duplex standard, switching between transmit and receive is done automatically and no further signal (such as RTS) is required. PH485RPX™ supports Point-to-Point and Point-to-Multi Point Party Line network topologies.
