Mitsubishi alpha 2 User Manual

α 2 Simple Application Controllers
AL2-2DA (AL2-14MR-*, AL2-24MR-*) 11
ENG-56
11.2 Specification
Note
1) When the external load resistance is 5kΩ to 1MΩ, the overall accuracy of the voltage
output is adjusted t
o “+/-1%”.(Factory calibration point is 10kΩ external load)
If the load resistance is smaller than 5k
Ω, the output voltage becomes smaller than the
correct value.
2) If the current output mode is used, an external load resistance of 500
Ω or less must be
used.
If the load resistance exceeds 500
Ω, the output current will be lower than the correct
value.
