Title: Using Analog I/p As for Digital Inputs.
Post by: shyampras on May 03, 2007, 02:50:13 AM

Hi,

I am using T100MD888 for material handling application. I am running short of Digital Inputs.

I plan to use Analog Inputs (the application does not demand for any analog signal processing).

Can i connect Digital inputs (volt free relay contact) between +5V DC, available at pin 13/15 and pin 8 - 1.

Regards,

Shyam Prasad

Certainly. You can connect +5V to the analog input when it is to be turned ON and connect 0V to the analog input when it is to be turned OFF (you can use a pull down resistor too). Then the PLC program only need to read ADC(n) and if the value is above 4000 it means it is ON and below 100 it is OFF.
