Description
+10V Locally pr10.5V power supply
AI1

Input range: AI1 voltage/current can choose 0
–10V / 0–20mA; AI2: -10V –
+10V;
 Input impedance: 20kΩ during voltage input; 250Ω during current input;

Whether the input is voltage or current is set through P05.50;

Resolution ratio: When 10V corresponds to 50Hz, the min. resolution ratio is
5mV;
