Connecting EZ DC analog inputs
The EZ-AB, EZ-DA and EZ-DC basic units are provided with
analog inputs. Inputs I7 and I8, and if present I11 and I12, can
be used to connect analog voltages ranging from 0 V to 10 V.
A simple additional circuit also allows the analog evaluation of
currents from 0 to 20 mA. The analog input signals are
converted to 10-bit digital signals.
The following applies:
• 0 V DC corresponds to a digital 0.
• 5 V DC corresponds to a digital value of 512.
• 10 V DC corresponds to a digital value of 1023.
