Selain dapat mengolah sinyal digital, PLC juga dapat mengolah sinyal analog.  Modul ini biasanya didesain untuk membaca sinyal-sinyal standard industri yakni 0 – 5 V, ±10 V, atau 4 – 20 mA. Untuk menggunakan analog input, modul ini harus dihubungkan ke rangkaian PLC dan ditentukan  Unit No. -nya. Unit No. ini ditentukan dengan cara mengatur skrup  Mach No.  di depan Modul Analog Unit. Skrup Mach No. ini ada 2 buah: satu skrup puluhan ( x10¹ ) dan satu skrup satuan ( x10° ). Jika ingin membuat modul ini memiliki Unit No. 12, putar skrup puluhan ke angka 1 dan skrup satuan ke angka 2. Selain itu, di IO Table dan Unit Setup pada CX-Programmer juga harus diberi Unit No. yang sama. Ingat, Unit No. modul ini tidak boleh sama dengan modul lain karena akan bertabrakan pengalamatan memorinya. Gambar 7 Terminal Modul Analog input (No. Unit) Pengalamatan nomer modul bisa dilihat pada table berikut: Switch setting Unit number Word allocated in special I/O uni...

ada Modul output PLC ada tiga jenis output PLC yang juga populer di pasaran, yaitu: Relay, Transistor, Triac. §    output Relay output PLC jenis relay adalah yang paling fleksibel penggunaannya karena dapat menggerakkan beban AC maupun DC. kelemahannya terletak pada tanggapan  switching-nya  yang relatif lambat (sekitar 10 ms ), dan akan mengalami kerusakan setelah beberapa juta siklus  switching.              Gambar 4 rangkaian internal output PLC Jenis relay Besar rating arus untuk setiap terminal umumnya tidak boleh melebihi 2 A untuk tegangan 220 volt (untuk lebih jelasnya dapat dilihat pada manual PLC yang digunakan). Bila batas besar rating arus ini dilampaui, akan menimbulkan kerusakan pada modul output nya. Jika keluaran yang akan dikontrol merupakan beban yang relatif besar (mengalirkan arus dengan jumlah besar) maka akan lebih aman jika output relay ini mengontrol beban tersebut lewat relay luar. § ...

Modul input / output PLC pada dasarnya adalah antarmuka yang mengoneksikan  PLC dengan peralatan input / output luar. Lewat sensor-sensor yang terhubung dengan modul ini, PLC mengindra besaran-besaran fisik (posisi, gerakan, level, arus, tegangan) yang terasosiasi dengan sebuah proses atau mesin. Berdasarkan status dari input dan program yang tersimpan di memori PLC. Secara fisik, rangkaian input/output dengan unit CPU tersebut terpisah Secara kelistrikan. Hal ini untuk menjaga agar kerusakan pada peralatan input output tidak menyebabkan terjadinya hubung singkat pada unit CPU. isolasi rangkaian modul dari CPU ini umumnya menggunakan rangkaian otocoupler                Gambar 1 rangkaian internal input PLC dengan input tegangan DC Gambar 2 rangkaian internal input PLC dengan input tegangan AC Gambar 3 rangkaian internal input PLC dengan input tegangan AC/DC Dari gambar 1 sampai gambar 3, terlihat bahwa secara fisik rangkaia...

WEISS Precision Systems In many applications of micro-assembly, electronics or laser technology, the trend is towards ever smaller structures.
