-10 to 10VDC
(Input resistance value: 1Mor more)
0 to 20mADC
(Input resistance value: 250)
16-bit signed binary
(Normal resolution mode: -4096 to 4095,
High resolution mode: -12288 to 12287, -16384 to 16383)
As concept of gain value is
changed, refer to Q68AD-G
[User’s Manual] and then,
confirm the I/O characteristics.
±0.1%
Normal resolution mode: ±4digit
High resolution mode (0 to 10V, -10 to 10V): ±16digit
High resolution mode (Other than the above ranges): ±12digit
Temperature coefficient: ±71.4ppm/°C (0.00714%/°C)
10ms/channel
(Sampling cycle)
The conversion speed of
Q68AD-G to A68AD has
become slow. If fast
conversion speed is required
for control, the Q64AD is
recommended.
