How do the Analog Inputs work?
Analog Inputs are available on DC powered units. The input will accept a 0-10VDC analog signal from many different sensors. The resolution of the input is 8 bits. This means the Millenium will ‘see’ a number between 0 and 255 representing the 0-10VDC span of the sensor. (0 VDC = 0, 10 VDC=255, 5 VDC = 128) 12 I/O Millenium II’s have 4 inputs that can be configured as analog or digital, 20 I/O units have 8 inputs that can be configured as analog or digital. The GAIN function block allows you to scale the 0-255 number from the analog input into units that match your application. Temperature can be displayed in C or F, pressure in PSI and so on.
