Phoenix Contact PSM-ME-RS485/RS485-P – 2744429 RS-485 Repeater

Phoenix Contact PSM-ME-RS485/RS485-P dengan item number 2744429 adalah compact RS-485 repeater yang dirancang untuk meningkatkan jangkauan dan keandalan jaringan RS-485 2-wire. Perangkat ini berfungsi sebagai interface converter dan repeater dengan 3-way electrical isolation antara power supply, RS-485 interface A, dan RS-485 interface B. Dengan fungsi segmentasi bus, repeater dapat membantu memperluas cakupan jaringan sekaligus meningkatkan jumlah perangkat yang dapat digunakan dalam sistem komunikasi industri.

Modul PSM-ME-RS485/RS485-P mendukung komunikasi RS-485 sesuai EIA/TIA-485 dan DIN 66259-4 dengan transmisi half-duplex serta format UART/NRZ 10 atau 11 bit. Kecepatan transmisi dapat dikonfigurasi mulai dari 1.2 kbps hingga 1.5 Mbps, sementara panjang transmisi dapat mencapai 1200 meter, tergantung pada baud rate, sistem bus, dan jenis kabel. Perangkat juga memiliki automatic data-direction switching, transparent protocol support, serta termination resistor terintegrasi yang dapat dihubungkan sesuai kebutuhan jaringan.

Untuk instalasi panel industri, Phoenix Contact 2744429 menggunakan catu daya 18–30 V AC/DC dengan tegangan nominal 24 V AC/DC dan konsumsi arus tipikal 25 mA pada 24 V DC. Repeater memiliki desain slim dengan lebar hanya 22,5 mm, pemasangan pada DIN rail, koneksi COMBICON pluggable screw terminal, serta tingkat proteksi IP20. Rentang temperatur operasi mencapai -40 hingga +70 °C, sehingga sesuai untuk aplikasi industrial communication, Modbus/RS-485, automation network, machine building, dan sistem kontrol terdistribusi.
