MELSEC-Q
3 SPECIFICATIONS
1: Accuracy of offset/gain setting at ambient temperature
2: "digit" indicates a digital value.
3: Accuracy per temperature change of 1°C
Example) Accuracy when temperature changes from 25 to 30°C
0.05% (reference accuracy) + 0.00714 %/°C (temperature coefficient)
5°C (temperature
change difference) = 0.0857%
4: Current value indicates value of instant input current that does not break module inner electrical resistance.
5: For details on the I/O conversion characteristics, refer to Section 3.1.2 (1).
6: Maximum resolution in the user range setting.
