This operation manual describes the features of the following Analog Input
Units.
• 3G2A5-AD001 to 3G2A5-AD007
• C500-AD101
• C500-AD501
Analog quantities, such as temperature, pressure, power, and power factor, in-
put to an Analog Input Unit via a preamplifier or transducer are converted to digi-
tal values for input to the CPU Unit.
Analog signals from sensors are converted to 12-bit binary data by the 3G2A5-
AD001 to 3G2A5-AD005 Analog Input Units (resolution: 1/4095); or to 10-bit
binary data by the 3G2A5-AD006 and 3G2A5-AD007 Analog Input Units (reso-
lution: 1/1023).
Number of Input Points Per Unit
Each Unit can handle A/D conversion for either two or four input points.

Compatible Input Specifications
The Units are compatible with a variety of input specifications. Select the ap-
propriate Unit from the table below.
Input signal range
Voltage g
Current
This Unit converts analog signals from sensors to 12-bit binary data.
Number of Input Points Per Unit
Each Unit has eight input points. An separate input signal range can be set for
each input point, to permit the simultaneous use of sensors with different output
forms.
Input Signal Ranges
The input signal ranges can be set as required between 0 and 10 V for a voltage
input or between 0 and 20 mA for a current input.
Many Features
In addition to A/D conversion, the Analog Input Units offer peak hold, mean val-
ue, scaling, and disconnection detection functions.
High Accuracy and High Speed
The C500-AD101 achieves a resolution up to 1/4095 and a conversion time of
10 ms max. per point.
The I/O READ and I/O WRITE instructions, READ and WRIT, can be used to
transfer data with the CPU Unit, thereby simplifying program creation and
achieving high-speed processing with batch transfer.
