Notes
Always make sure the switch settings and the terminal base
wiring connections match. For output, in particular, if the
settings and the wiring connections are wrong, the control
unit will output values like those shown below, even in the
PROG. mode. (For information on switch settings,
see page 4-3)

DA internal block diagram
A voltage amplifier and current amplifier are connected in
parallel to a single DA converter IC.

Also, the digital value that is sent to the DA converter IC to
achieve a voltage output of 0V is different from that input to
the DA converter IC to achieve a current output of 0mA.
As a result, if the voltage output is set to 0V, 10mA is output
from the current output terminal, and conversely, if the current
output is set to 0mA, 10V is output from the voltage output
terminal.
