You can select the input specifications of
terminal 2 (0 to 5V, 0 to 10V, 0 to 20mA)
and input specifications of terminal 1 (0 to
±5V, 0 to ±10V).
To change the terminal 2 to the voltage
input specification (0 to 5V/ 0 to 10V), turn
OFF (initial status) the voltage/current
input switch 2. To change it to the current
input (0 to 20mA), turn ON the voltage/
current input switch 2.
Override and reversible operation can be
selected.
