The inverter provides user power; the maximum output current is 200mA
COM
Common port of + 24V
+ 10V
10V reference power supply
Max. Output current: 50mA
AI2
1. Input range: AI2 voltage and current can be chosen: 0 – 10V / 0 – 20mA; AI3: -10V
– + 10V
2. Input impedance: voltage input: 20kΩ; current input: 500Ω
3. Voltage or current input can be set by toggle switch
4. Resolution: the minimum AI2 / AI3 is 10mV / 20mV when 10V corresponds to
50Hz
AI3
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
