Analog signal configuration
Size 1 … 4
1 = DIP switch: left = I / right = V
AIN2:
I
= Current 0/4 … 20 mA
V
= Voltage
AIN1:
I
= Current 0/4 … 20 mA
V
= Voltage
Above Size 5:
1 = DIP switch: left = ON / right = OFF
S4:
AIN2:
ON
= ± 10 V
OFF
= 0 … 10 V
S3:
AIN1:
ON
= ± 10 V
OFF
= 0 … 10 V
S2:
AIN2:
I
= ON = current 0/4...20 mA
V
= OFF = voltage
S1:
AIN1:
I
= ON = current 0/4...20 mA
V
= OFF = voltage
Note:
If S2 = ON (AIN2 = Current input), S4 must be = OFF.
If S1 = ON (AIN1 = Current input), S3 must be = OFF.
