DIGITAL RESISTANCE CONTROLLER HAVING AUTOMATIC CONTROL FUNCTION

摘要

PURPOSE: A digital resistance controller having an automatic control function is provided to automatically control a resistance value without using an additional control system when a desired output value is set. CONSTITUTION: A digital resistance controller includes a digital array resistor(20), a communication unit(10), a digital processor(30), ROM/RAM(40), and an LCD(50). The digital array resistor(20) embodies the characteristic of a variable resistor. The communication unit(10) is connected to the digital array resistor(20) and sets a resistance value by a communication method. The digital processor(30) automatically controls an output resistance value of the digital array resistor(20) by a feedback signal(60). The digital processor(30) performs an internal set function. The LCD(50) displays the resistance value of the digital array resistor(20).
