Configuration of analog signals
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.
