Specifications Section 5-1
Note 1. Do not apply a voltage higher than 600 V to the terminal block when per-
forming withstand voltage test on this Unit.
2. Refer to Dimensions on page 359 for details on the Unit’s dimensions.
3. 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 power supplies are recommended.
S82K-05024: 100 VAC, 50 W
S82K-10024: 100 VAC, 100 W
S82J-5524: 100 VAC, 50 W
S82J-5024: 100 VAC, 100 W
4. Data exchange methods with the CPU Unit are as follows:
5. Output signal ranges can be set for each output.
6. The accuracy is given for full scale. For example, an accuracy of
±
0.3%
means a maximum error of
±
12 (BCD) at a resolution of 4,000. For the
CJ1W-DA021/041, the accuracy is at the factory setting for a current out-
put. When using a voltage output, adjust the offset gain as required.
7. D/A conversion time is the time required for converting and outputting the
PLC data. It takes at least one cycle for the data stored in the PLC to be
read by the Analog Output Unit.
8. When the operation mode for the CPU Unit is changed from RUN mode or
MONITOR mode to PROGRAM mode, or when the power is turned ON,
the Output Conversion Enable Bit will turn OFF. The output status specified
according to the output hold function will be output.
9. The CJ1W-DA08V/08C can be set to a conversion cycle of 250
µ
s and a
resolution of 8,000 using the setting in D(m+18).
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. (See note 8.)
In adjustment mode, when a value other than the output number is output during adjustment.
When there is an output setting error or a fatal error occurs at the PLC. (See note 10.)
When the CPU Unit is on standby.
When the Load is OFF.
Scaling function 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.
(With the CJ1W-DA08V/DA08C, this function is enabled only for a conversion time of 1.0 s and a reso-
lution of 4,000.)
