TROUBLESHOOTING
*1 Accuracy of offset/gain setting at ambient temperature
Q66AD-DG needs to be powered on 30 minutes prior to operation for compliance to the
specification (accuracy).
*2 "digit" indicates a digital value.
*3 Accuracy per temperature change of 1°C
*4 User range setting is 2 to 24mA
*5 The cycle in which A/D conversion values are updated.
*6 The time required for an input signal to reach the A/D converter inside the Q66AD-DG.
*7 Current value indicates value of instant input current that does not break module inner electrical
resistance.
*8 For details on I/O conversion characteristics, refer to Section3.1.2 (2).
*9 The maximum resolution for the user range setting
*10 The external power supply is for a 2-wire transmitter.
When all the channels used are for current input, wiring for 24VDC is not required.
Note that to use the Q66AD-DG with a product number (first five digits) of 15031 or earlier, refer to
Appendix 2.
See the user's manual for the CPU module being used for general specifications
of the A/D converter modules.
Internal current consumption (5VDC) 0.42A
Weight 0.22kg
Example) Accuracy when temperature changes from 25 to 30°C
0.1% (reference accuracy) + 0.00714 %/°C (temperature coefficient) 5°C
(temperature change difference) = 0.1357%
