(5) Analog input/output board NA3AW03-MR
*1 The overall accuracy is the specication for when noise described in “Electrical service conditions” is not applied.
If noise is applied, the overall accuracy may exceed the above specication.
*2 Tightening torque for mounting the board on the main unit: 0.2 N·m
*3 Notes on using analog input
If connection between the analog unit and an external analog device is broken, the A/D conversion value (analog input
value) becomes 0 (zero).
*4 Notes on using analog output
The analog unit does not support the hold function. If the main unit stops due to a system error, the analog output value
becomes 0 (zero). It is not possible to hold the output status after occurrence of an error or CPU stop.
