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
Impetance when AI2 = input current signal:
•
