Description
CN2
AI2 can select voltage or current signal:
•
Pin 1& 2 are short-connected, AI2 inputs voltage signal (factory setting);
•
Pin 2 & 3 are short-connected, AI2 inputs current signal.
CN4
In interferential occasion, connecting PE and COM can increase immunity.
•
Pin 1 & 2 are short-connected, PE and COM are not connected (factory setting);
•
Pin 2 & 3 are short-connected, PE and COM are connected.
CN5
In interferential occasion, connecting PE and GND can increase immunity.
•
Pin 1 & 2 are short-connected, PE and GND are not connected (factory setting);
•
Pin 2 & 3 are short-connected, PE and GND are connected.
CN6
Impedance selection when AI2 = current input:
•
Pin 1 & 2 are short-connected, impedace = 500Ω (factory setting);
•
Pin 2 & 3 are short-connected, impedace = 250Ω.
CN7
AO1 can select output voltage or current signal.
•
Pin 1 & 2 are short-connected, AO1 outputs voltage signal(factory setting);
•
Pin 2 & 3 are short-connected, AO1 outputs current signal.
CN8
AO2 can select output voltage or current signal.
•
Pin 1 & 2 are short-connected, AO2 outputs voltage signal (factory setting);
•
Pin 2 & 3 are short-connected, AO2 outputs current signal.
CN9
Matching resistor selection for SCI communication:
•
Pin 1 & 2 are short-connected, do not use matching resistor (factory setting);
•
Pin 2 & 3 are short-connected, use matching resistor.
CN15
Voltage selection for analogue power input:
•
Pin 1 & 2 are short-connected, input voltage = +10V (factory setting);
•
Pin 2 & 3 are short-connected, input voltage = +5V.
