Serial RS485/RS422 Repeater & Isolator


IP Electronix PH485Y11 is a Serial RS485 and RS422 Repeater and Isolator. If it is needed to have RS485/RS422 network with length more than 1200m or to have more than 32 nodes, using a PH485Y11 helps you to increase the network length up to 2400m and also to have up to 64 devices connected to it. PH485Y11 is compatible with RS485 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 1W) consumption.

Since RS485 is a Half-Duplex standard, switching between transmit and receive is done automatically and no further signal (such as RTS) is required. PH485Y11 supports Point-to-Point and Point-to-Multi Point Party Line network topologies.

Protection against Surge, ESD and EMI is considered in its design and also has 3kV insulation between RS485/RS422 sides, so PH485Y11 is good for industrial usage and is useful for Industrial Automation, Telecommunications, SCADA Systems, and DCS Systems …
