The following table details the I/O connector pinout:  
PIN  Description  PIN  Description 
1  Common Input GND  9  Common Output 
2  Common Input GND  10  Common Output 
3  Input 1 +  11  Output 1 
4  Input 2 +  12  Output 2 
5  Input 3 +  13  Output 3 
6  Input 4 +  14  Output 4 
7  Input 5 +  15  Output 5 
8  Input 6 +  16  Not connected 
 
To activate the input 1, provide a 12 VDC ÷ 24 VDC between the “Input 1 +”and the “Common Input 
GND“; the input current required by the input is a maximum of 20 mA. 
The five outputs are relays, with a common pole “Common Output”. The outputs can work up to +24 
VDC, with 1 A maximum current. 
The inputs and outputs status is shown by the LEDs on the QATnode. 
Here is an example of a connection, in which six switches are used to command the inputs and five lamps 
are use to monitor the output status:
