A programmable logic controller (PLC) or programmable controller is a type of computer used for automating of electromechanical processes. This may mean the control of machinery on factory assembly lines, amusement rides, or lighting fixtures. PLCs are used in a large variety of industries and for many machines. One thing that separates them from general-purpose computers, PLCs are designed for multiple inputs and output arrangements, extended temperature ranges, resistance to vibration and impact and immunity to electrical noise. The programs that control machine operation are typically stored in battery-backed or non-volatile memory. The PLC is a prime example of a real time system or RTS because output results must be produced immediately in response to input conditions within a certain amount of time, otherwise unintended operation will occur.
Because PLCs usually store their programs using battery backup, the importance of the batteries themselves take on a tremendous amount of importance. Therefore, when operating these computers, it is extremely important to have a reliable source for the afor mentioned batteries. PQBattery.com fits the bill as a reliable, cost effective supplier of these valuable batteries that are necessary for the operation of your valuable PLCs.
