Switch configuration
Label Switch Name Description
Ai1
(SW1)
Analog input 1
switch
It changes the input specification of Analog input 1
(Ai1 terminal).
10V: Voltage input is available.
20mA: Current input is available.
Ai2
(SW2)
Analog input 2
switch
It changes the input specification of Analog input 2
(Ai2 terminal).
10V: Voltage input is available.
20mA: Current input is available.
Ao1
(SW3)
Analog output 1
switch
It changes the output specification of Analog output 1
(Ao1 terminal).
10V: Voltage output is applied.
20mA: Current output is applied.
Ao2
(SW4)
Analog output 2
switch
It changes the output specification of Analog output 2
(Ao2 terminal).
10V: Voltage output is applied.
20mA: Current output is applied.
P.SEL
(SW5)
Power supply
input switch
It changes the power source for input terminals.
IN: Internal power source.
EX: External power source.
(While setting EX, it requires an external power supply
between input terminals and COM terminal)
SRC/SINK
(SW6)
Input terminal
Sink/Source
logic switching
It changes the sink or source logic for input terminal.
Is enabled when SW5 is in IN position.
SINK: Switch to Sink logic.
SRC: Switch to Source logic.
