Analog Output Units CJ1W-DA021/DA041/DA08V/DA08C/DA042V
Specifications
*1 Do not apply a voltage higher than 600 V to the terminal block when performing withstand voltage test on this Unit.
*2 The maximum number of Analog Output Units that can be mounted to one Rack varies depending on the current consumption of the other
Units mounted to the Rack.
Select a 24 VDC power supply based on the surge current. The following OMRON external power supplies with a power rating of 50 W are
recommended.
*3 Output signal ranges can be set for each output.
*4 The accuracy is given for full scale. For example, an accuracy of ±0.3% means a maximum error of ±60 mV for a 10 to 10 V range. For the
CJ1W-DA021/041, the accuracy is at the factory setting for a current output. When using a voltage output, adjust the offset gain as required.

functions
Output hold function
Outputs the specified output status (CLR, HOLD, or MAX) under any of the following circumstances.
When the Conversion Enable Bit is OFF. *6
In adjustment mode, when a value other than the output number is output during adjustment. *7
When output setting value error occurs or Controller operation stops.
When the Load is OFF.
Scaling ---
Supported only for a conversion period of
1 ms and resolution of 4,000.
Setting values in any specified unit within a
range of ±32,000 as the upper and lower
limits allows D/A conversion to be execut-
ed and analog signals to be output with
these values as full scale.
Setting values in any specified
unit within a range of ±32,000
as the upper and lower limits
allows D/A conversion to be
executed and analog signals to
be output with these values as
full scale.
Offset/gain adjustment Supported ---
Direct conversion ---
D/A conversion is performed
and the output value is re-
freshed when the ANALOG
OUTPUT DIRECT CONVER-
SION instruction (AODC) is ex-
ecuted. This instruction is
supported by the CJ2H-
CPU@@ (-EIP) CPU Units with
unit version 1.1 or later, and
CJ2M-CPU@@.
CJ1, NJ501, and CP1H CPU
Units and NSJ Controllers do
not support direct conversion.
