Connect analog DC inputs

The CL-AC1, CL-AC2 and CL-DC2 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 signals apply:
• 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.
