Analog input and
output
AI1
Analog input 1
1. Input range: AI1 voltage and current
range: 0–10V, 0–20mA
2. Input impedance: 20kΩ during voltage
input; 250Ω during current input
3. Voltage or current input is set through
the jumper.
4. Resolution ratio: When 10V corresponds
to 50Hz, the min. resolution ratio is 5mV
5. Deviation: ±1% when the input reaches
full the measurement range at 25°C
