<div style="font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px; text-align: justify;"><span class="Apple-style-span" style="background-color: white; font-size: x-small;">PLC adalah komponen elektronika yang menggantikan fungsi dari relay dengan kemampuan yang lebih luas dari relay itu sendiri. PLC mampu melekukan operasi aritmatika (perhitungan), konversi (perubahan) analog-digital, dll. dengan demikian konsep yang digunakan pada PLC sama dengan konsep yang digunakan pada rangkaian relay.</span></div><div style="font-family: Arial, Tahoma, Helvetica, FreeSans, sans-serif; font-size: 13px; text-align: justify;"><span class="Apple-style-span" style="background-color: white; font-size: x-small;"><br />
