Conversion time (See Note 2.) 10 ms/Unit max.
Isolation method Photocoupler isolation between I/O terminals and PC
(There is no isolation between the analog I/O signals.)
Note: 1. The voltage output and current output can be used at the same time, but the total output current cannot exceed 21 mA.
2. The conversion time is the total time for 2 analog inputs and 1 analog output.
