+ 10V
10V reference power supply
AI1
1. Input range: AI1 voltage / current can choose 0–10V / 0–20mA
AI2: -10V – +10V voltage
2. Input impedance: 20kΩ during voltage input; 250Ω during current input
3. Voltage or current input can be set by parameters
4. Resolution ratio: When 10V corresponds to 50Hz, the Min. Resolution ratio is 5mV
5. 25 ° C, When input above 5V or 10mA, the error is ± 0.5%
AI2
GND
Analog reference ground
AO1
1. Output range: 0–10V voltage or 0–20mA current
2. Voltage or current output is set by toggle switch SW2
