Features
C500-AD501
1-1-2 Analog Output Units
Basic Function
Features
This Analog Input Unit converts analog voltage or current signals from sensors
to signed BCD data or to binary data (with two’s complements used for negative
values). A microprocessor is built into the C500-AD501 to enable advanced data
processing in the Analog Input Unit before transferring the data to the CPU Unit.
Number of Input Points Per Unit
Each Unit has sixteen 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 as follows:
Many Features
In addition to A/D conversion, the Analog Input Units offer scaling, filtering, aver-
aging, peak hold, upper/lower limits, and input range high/low alarms. These
functions can be set separately for each input point. Executing these function in
the Analog Input Unit greatly reduces the load on the ladder program and the
CPU Unit.
High Accuracy and High Speed
The C500-AD501 achieves a resolution up to 1/4095 and a conversion time of
25 ms max. per 16 input points. (The use of the above special function will in-
crease the conversion time.)
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. A Pointer Word can also
be set to limit the words being read or written to further increase speed.
Built-in EEPROM
An EEPROM is built into the C500-AD501 to enable storing parameters. The pa-
rameters stored in EEPROM are transferred to RAM at the start of operation be-
fore beginning actual operation.
This operation manual describes the features of the following Analog Output
Units.
• 3G2A5-DA001 to 3G2A5-DA005
• C500-DA101/103
• C500-DA501
Conversion of PC digital output signals to analog signals to drive instruments
and devices requiring an analog input.
These Units convert 12-bit binary data with a resolution of 1/4095 to analog sig-
nals.
Number of Output Points Per Unit
Each Unit can handle D/A conversion for two output points.
Voltage inputs: 0 to 5 V, 0 to 10 V, –5 to 5 V, or –10 to 10 V
Current inputs: 0 to 20 mA or –20 to 20 mA
