Abstract
Servo valve hidrolik adalah valve yang berfungsi untuk mengatur oli yang akan masuk pada ruang hidrolik dan digunakan untuk mengendalikan arah dan besar pergerakan dari aktuator hidrolik suatu peralatan. Sistem hidrolik memiliki karakteristik, gaya yang kecil dapat digunakan untuk menggerakkan atau mengangkat beban berat dengan cara mengubah perbandingan luas penampang silinder. Saat ini driver servo valve dan servo valve pada modul elektro hidrolik yang ada di departemen Teknik Elektro Otomasi sedang mengalami kerusakan.
Modul Elektro Hidrolik Servomechanism (EHS 160) dapat dikendalikan menggunakan mikrokontroller dan rangkaian driver servo valve amplifier yang terdiri atas rangkaian zero-span dan rangkaian push-pull komplementer. Komputer sebagai memberi nilai set point akan memberi perintah kepada mikrokontroller, mikrokontroller yang mengeluarkan sinyal digital. Sinyal digital yang dihasilkan, diberi rangkaian pengondisi sinyal (signal conditioning) guna memberi sinyal perintah ke servo amplifier. Didalam servo amplifier terdiri atas rangkaian Zero-Span dan rangkain push pull komplementer yang digunakan mengatur arus yang akan keluar dari servo amplifier dengan range -100mA hingga +100mA pada resolusi tegangan -2 hingga +2v.
Perancangan dan penerapan driver servo valve hidrolik ini telah dapat digunakan untuk mengendalikan servo valve pada modul Elektro Hidrolik Servomechanism (EHS 160). Rangkaian zero-span yang bertugas mengkonversi tegangan masukan 0 V – 3,33 V tegangan keluaran -2 V hingga +2 V. Rangkaian push-pull komplementer yang digunakan sebagai penguat daya dan arus guna mengendalikan kinerja dari servo valve dengan arus yang dapat dihasilkan -85mA hingga +80mA.

Hydraulic servo valve is a valve that serves to regulate the oil that will enter in the hydraulic chamber and is used to control the direction and magnitude of the movement of the hydraulic actuator of an apparatus. Hydraulic systems have characteristics, small forces can be used to drive or lift heavy loads by changing the ratio of the cross-sectional area of the cylinder. Currently the driver servo valve and servo valve in the existing electro hydraulic module in the Department of Electrical Engineering Automation is being damaged.
Electro Hydraulic Servomechanism (EHS 160) module can be controlled using microcontroller and driver servo valve amplifier circuit consisting of zero-span circuit and complementary push-pull circuit. The computer as giving the set point value will give the command to the microcontroller to issue a digital signal. The resulting digital signal, given a signal conditioning circuit to signal commands to the servo amplifier. Inside the servo amplifier consists of a Zero-Span circuit and complementary push pull circuits that are used to regulate the outflow of servo amplifiers with a range of -100mA to + 100mA at a voltage resolution of -2 to +2v.
The design and application of this hydraulic servo valve driver can be used to control the servo valve in the Electro Hydraulic Servomechanism (EHS 160) module. Zero-span circuit in charge of converting input voltage 0 V - 3.33 V output voltage -2 V to +2 V. Complementary push-pull circuit used as a power amplifier and current to control the performance of servo valve with the current that can be generated - 85mA to + 80mA.
