Analog output modules
Analog output modules convert a digital value from the PLC CPU into an analog voltage or cur-
rent signal that can be used to control an external device (digital/analog conversion or D/A
conversion).
The analog output signals generated by the MELSEC System Q use the standard industrial
ranges of 0–10V and 4–20mA.

Depends on the thermo-
couple used
The resolution of 0.333 mV respectively 0.83 µA and the extremly short
conversion time of 80 µs per output channel are only two of the many fea-
tures of this modules. Isolation between process and control by means
of opto-couplers is also a standard feature.
